D is inferior to A for two reasons

1: yet discovered ( this part was eliminated in choice D)

then choice D conveys a different meaning that fossils of feathered dinosaurs will offer the most dramatic one without being challenged by any subsequently found evidence ( the change of meaning is unacceptable)

2. offer vs have offer

the previous one is used to describe sth that does not restrict to any time-frame ( a timeless fact)

here means that the evidence will continue to provide this evidence for ever

the latter one is somewhat suggesting that the evidence will be invalid in the future time-frame

the original meaning is fine, you cannot change it without any justifications

我在网上搜到了另外一个版本。选项D和这个不一样：D. have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds that have yet been discovered 。如果是这个D，那么D明显是错的。如果你post的这个D，我觉得用不用完成时都对，只不过D里面少了yet discovered，而这让A更好。
