I think the reason is Argon is the only inert gas which cannot exists in free state compared to other inert gases.

Shubham said: (Jul 27, 2011)  
Yeah its true because argon is not reactive gas.

Resmy Aneesh said: (Apr 25, 2012)  
Argon inert gas. It is the third most abundant in atmosphere. In atmosphere 93% of argon is there.

Ris said: (Jul 7, 2012)  
How can it be abundant and rare at the same time ?

Lawrance said: (Sep 14, 2012)  
Argon is fourth aboundent element in earth atmosphere Nitrogen78%, oxygen21%, corban di oxide.03%, and ARGON.93% so, in this Q. Argaon is correct.

Martins said: (Nov 7, 2012)  
Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm), making it approximately 23.8 times as abundant as next most common atmospheric gas.

Nkemzi said: (Nov 24, 2012)  
Helium should be the most abundant noble gas due to the emission of alpha particles by radioactive substances. The alpha particles in turn ionize air particles to form helium gas.

Subu Sharma said: (May 4, 2013)  
Argon is not a reactive gas then others gases.

Radhakrishnakompalli said: (Jun 12, 2013)  
Rare gas is another name for inert gas. So it is most abundant inert gas in earth atmosphere.

Sundaram said: (Sep 20, 2013)  
Argon is noble gases. It is present in less amount in atmosphere.

Manasa said: (Nov 13, 2014)  
Argon is a inert gas. It occurs in the earth crust 93%.

So for this question Argon is correct.

Manasa said: (Nov 13, 2014)  
Argon is the inert gas. It is the most abundant rare gas in the atmosphere because it occurs in the earth crust with 93%.

It is a not reactive element. So for this questions Ar is the correct.

Sunil said: (Feb 27, 2015)  
Nitrogen 78%,
Oxygen 21%,
Carbon di oxide 0.03%,
Argon 0.93%.
Ne 0.0018%.
He 0.0005%.
Ozone 0.00006%.

So answer correct is helium.

Nayan said: (May 11, 2015)  
Yes. Argon is not reactive gas like other noble gas.

Asifa said: (Jun 18, 2016)  
Which one is the most reactive gas?

Devill said: (Nov 29, 2016)  
@Lawrence and @Ris are correct. Also, agree that argon is 0.93% and is rarest.

G.Sri Harshini said: (Jun 27, 2017)  
I think All options are Noblegases.

Bharat said: (Nov 26, 2017)  
I think all are inert gases but abundant rare is only argon.

Tella Salman said: (Feb 6, 2018)  
Argon is the most abundant noble gas in the atmosphere.

There's so much Ar in the atmosphere because most of it was produced by a long-lived radioactive isotope of potassium in the earth's crust and released over geologic time.

Mchuddlestone said: (Mar 18, 2018)  
I think the Question should be as 'noble gas' instead of 'rare gas'.

Surya Kiran said: (Sep 25, 2020)  
Argon is present in tube light!
