Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored due to their enhancement of reproduction or survival, but that they are simply random by-products of other evolutionary developments.

(A) due to their enhancement of reproduction or survival, but that they are
(B) due to the reproduction or survival they enhance, but they are
(C) because they enhance reproduction or survival, but
(D) because they enhance reproduction or survival, but are
(E) because of enhancing reproduction or survival, but are

IMO E.

stephen has argued that many .......are not product of.............., but are simply random by products of ..................

Now though .......because they enhance reproduction or survival ....is better consturction than .......because of enhancing reproduction or survival

But they is not clear in D. It could refer to traits or products.....
Hence E

there is one problem with D.

"not the products of natural selection,................. " is not parallel to "but are simply random by-products ...............".

hence IMO C.
