It is B.

Permanent wilting point is the correct answer.

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.

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.

Permanent wilting point is the correct answer.

Please explain the right answer.

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.

@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.

The correct answer is the maximum efficiency of soil moisture. So it's none of the above.

I think the answer is parmanent wilting point.

The answer is given wrong. The right answer is permanent wilting point.
