Between A and C. Not sure if (C) changes the meaning (does not have 'appoximately'). It depends on how one interprets the sentence. Would go for (A).

I go for C, but I agree w/ eyunni, not sure if it changes the meaning.

I realized from another post: 'estimate - approximately' is redundant. (C) it should be.

The OA is C. Why? because in the original sentence, the word "estimate" and "approximately" are redundant. Also, although using either "that study" or "who study" could be appropriate, using the present participle "studying" is generally considered more concise.

crap, fell for A. Missed the redundancy!

Also, D and E are out immediately because of the which towards the end.
