@All.
DNA has H at carbon two, RNA has oh at carbon, if a molecule doesn't have a hydrogen which is the same thing as "lacking" then we can eliminate DNA. What's left is RNA?
Anyone, please clarify this in detail.

I agree @Josh.
Because in this question said the lacking of h on C2 means lacking of hydrogen atom So it's clear that RNA lack H at carbon 2 and having OH group.
Or the other sense both have one hydrogen at C 2 but RNA also contains OH in case of DNA its contain H so RNA lack hydrogen in another side of carbon.

I think the question is wrong for the indicated answer.
DNA lacks OH at 2 C group not H.
DNA lacks OH at 2 C group not H.

The question is absolutely right DNA lack the hydrogen atom at 2 carbon group whereas in RNA the hydroxyl group is present.

Its oxygen that is absent.

Yes, question is incorrect for the indicated answer.
A five carbon sugar lacking a hydrogen at number 2 carbon is found in: RNA ( hydroxyl groups).
A five carbon sugar with a hydrogen at number 2 carbon is,
found in: DNA ( Deoxyribonucleotide - has 2 H's).

In question itself 'Oxygen' should replace at 'Hydrogen'. The sugar in DNA is 2-deoxyribose, means oxygen lacking at 2nd carbon ribose.
