A is not great.. but best among them.

All other options.. even make setences worse..

B,D,E --> distorts the meaning.

c .. showed is incorrect.

I agree, (A)

Thanks guys

OA is indeed A

But Don't you think that A is a example of Comma splice .

Ic + , + IC

I am confused between A and C. Can some one plz explain

deep wrote:I am confused between A and C. Can some one plz explain

The tense of the verbs must agree.

With C it says "Chinese scientists showed" meaning past tense, but the rest of the sentence says "Birds' feathers appear" appear is in present tense.

Choice A however says "Chinese scientists have shown". I know this may be confusing and I can't think of a good way to explain it but this almost can be present tense as well as past tense.

Choice C almost can be interpreted as the scientists showed, at ONE particular point in time. But choice A can be interpreted as they have shown, and continue to show.

Hope this helps.
