I am voting for C.
Actually it is a tie between C & D. The "also" in D makes the meaning slightly different.

For "the ultrathin, layered construction of a butterfly’s " is singular
A - "are" is grammatically wrong
E - "enable" is grammatically wrong
B - "that" is redundantly used
D - "also" distorts the meaning.

Do let me know the OA.

my FA is D
I have rejected all other options based on the subj.-verb agreement.

Scientists have discovered <B>the ultrathin, layered construction</B>

the part in bold is singular and hence "also enables" should follow

D is best IMO. C actually changes the meaning as I don't believe that "iridescence" allows any heat retention. Rather, I believe that the "layered construction of the wings" allows that phenomenon

D is correct


A.wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling

should be is (subj: construction)

B: wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables

not idiomatic (should be same as ...)


C: wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling

changes meaning

E: wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable

should be enables

I will go with D for several reasons

-There should be an agreement between ultrathin and enalbes.

-layered construction of a butterfly’s wings is the noun clause that defines ultrathin

-the same construction that makes some butterflies shimmer via the phenomenon of iridescence, if a pronoune is used in this cluase, it will be confusing, is it refering to wing or construction. so the best way is to indicate the noun it self.

I hope my explaination will helps.[/b]

Good observation.
My wrong answer was due to my technical background;-) that led to unnecessary extrapolation.

BTW what is IMO?
