Scientists have recently discovered that the ultrathin, layered construction of a butterfly's wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling the insect to control how much heat energy is absorbed by its wings and how much is reflected away.

A. wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling
B. wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables
C. wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence,enabling
D. wings-the same construction that makes some butterflies shimmer via the phenomenon of iridescence-also enables
E. wings-of the same construction that makes some butterflies shimmer via the phenomenon of iridescence-also enable
