Chuchu said: (Jul 16, 2015)  
I think its option B permanent wilting point.

Jaish Choudhury said: (Aug 1, 2015)  
The answer is given wrong. The right answer is permanent wilting point.

Nageshwar said: (May 6, 2016)  
Answer should be Permanent Wilting point(PWP).

Papai said: (May 12, 2016)  
I agree with you all.

Answer is Permanent wilting point.

Abhra said: (Jun 3, 2016)  
No, the given answer is wrong.

Ranjan Patra said: (Jun 25, 2016)  
It should be a Permanent wilting point.

Baloch said: (Nov 2, 2016)  
Thank you all for clearing my doubt.

Manas Ranjan Nahak said: (Nov 26, 2016)  
I think the answer will be the permanent wilting point.

Dipak said: (Dec 20, 2016)  
It should be Parmanant wilting point.

Parimal Biswas said: (Jan 8, 2017)  
I think the answer is parmanent wilting point.

Ashish Tadewar said: (Mar 14, 2017)  
It's permanent wilting point.

Bilawal Siapad said: (Mar 16, 2017)  
It is permanent wilting point.

Ehsan Ali said: (May 11, 2017)  
I also think Option B is correct.

Rajat,Tanmay,Suman said: (Jun 6, 2017)  
The correct answer is the permanent wilting point.

Abhishek Shrivastava said: (Jun 20, 2017)  
Answer is correct because below or on PWP plant is not able to extract water. But plant is not able to extract sufficient water below optimum water content.

Kamal said: (Aug 24, 2017)  
I think the given answer is correct because PWP is the lowest point till which a plant can extract water from the soil.

So, at PWP plant can extract water though less.

Saifullah said: (Nov 18, 2017)  
Anyone can help me answer of this question.

Vishal Kumar said: (Dec 7, 2017)  
It should be Ultimate wilting point.

Nayan Ahir said: (Dec 12, 2017)  
Answer is right: None of these.

Because permeant wilting point= the water content at which plants can no longer extract sufficient water from the soil for it's growth.

Geek said: (Feb 27, 2018)  
Answer is ultimate wilting point, at which if the water is given to plant, than also it will not grow.

M. K. Jha said: (Apr 13, 2018)  
Answer is permanent wilting point or wilting co-efficient it is the water content at which plants can no longer extract sufficient water from the soil for its growth.

Orai said: (Jul 1, 2018)  
As per my knowledge:.

Option B) permanent wilting point is the right answer.

Gkp said: (Jul 18, 2018)  
Yes, the answer is B.

Ravi said: (Aug 4, 2018)  
Answer is correct none of these. The answer of this question is (optimum moisture content) at this stage plants fail to extract sufficient water for thier requirement.

Aqeel said: (Feb 14, 2019)  
The answer will be permanent wilting point.

Ref. Khurmi & Agor.

Er Nk said: (Mar 5, 2019)  
It is B.

Permanent wilting point is the correct answer.

Dr. Azmat Raza said: (Mar 10, 2019)  
Given answer is correct.

Here, it is asking not sufficient water so it will be optimum moisture content not pwp.

At the permanent wilting point there will be no extraction of water by the plant.

Arvind said: (Mar 19, 2019)  
Yes, the given answer is correct ie, option D, because below optimum moisture content plants fail to extract sufficient water for their requirements. Not permanent welting point because at pwp plants extract water from soil but is not sufficient for their requirements.

Gimi said: (May 4, 2019)  
Permanent wilting point is the correct answer.

Jitendra said: (May 15, 2019)  
Please explain the right answer.

Priyanka said: (Aug 10, 2019)  
Permanent wilting point (PWP) or wilting point (WP) is defined as the minimal amount of water in the soil that the plant requires not to wilt.

Kitkupar said: (Oct 21, 2019)  
Answer is none of the above correct answer is temporary wilting point (twp).

Opsc Aee said: (Nov 17, 2019)  
@Those who agrees with "none of these". please read the question carefully, it is asked about fails to extract sufficient water.

Permanent Wilting Point - the sufficient amount of moisture cannot be extracted by the plant roots, at this point wilting of the plant occurs.

Temporary Wilting Point - Plant recovers from temporary wilting after some time.

That means in TWP there may be the chance to recover but there is no chance to recover in PWP.

Answer - Permanent Wilting Point.

Jagbir Bm said: (Feb 23, 2021)  
The correct answer is the maximum efficiency of soil moisture. So it's none of the above.

Prasanth said: (Jun 21, 2021)  
Answer is correct because below or on PWP plant is not able to extract water. But plant is not able to extract sufficient water below optimum water content.
