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.

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.

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.

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.

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.

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

Rare gas is another name for inert gas. So it is most abundant inert gas in earth atmosphere.
