Sentence Correction

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

This question is easy, m interested to know the use of Punctuation "-" used after wings...when this type of Punctuation is used?? although one can find out the answer without even knowing the use of this Punctuation.

the "-" is construction which is normally used when you are refering to the amount. One example which I remember is this-

a) I have thirty-five pounds in my pocket.
b) I purchased one-litre of milk today.

OA is D and yes Op C is missing the verb

layered construction...adjective modifier and between the COMMA's can not contain the main verb, the subject ultrathin requires a main verb

A, E uses plural verb with singular noun

Yes D is correct and C is missing the verb.

i think "-" is just offsetting a modifier.

+1 to D

A dash ( "--" ) separates parts of the sentence, and can work the say way that commas, parentheses, and colons can. A hyphen ( "-" ) separates parts of a compound word, or syllables of a word that gets split between the end of one line of text and the next. Traditionally, hyphenation was the way of modifying a noun with another noun (which can normally only be done by adjectives); this is why in 100-year-old writing you will see things like "hand-bag" and "motor-car".

To add to that dash '-' is also use to exemplify or contradict an IC.

Example:

She was wearing a red skirt-or was it pink?
