Some people are saying it's C-Deeply personal. Although, to be honest, ALL literature is A because it depends on how you interpret it. That's why we have literature classes and 10 people can write 10 different opinions on what the literature is saying. Since contemporary simply means the writing written after WWII era, it can range so much, that saying it's deeply personal, in my opinion, is too broad. So I would say A, unless you have something in your reading/lessons that say otherwise, or gives a specific answer.
Nonrestrictive clauses are those which are set off by commas from the rest of the sentence. I'd choose the answer <u>which<em /></u> as the correct one, because yet introduces independent sentences, and that and while introduce restrictive clauses.
For example:
The price, which was very high for me, was quite reasonable for Frank.<u />
The correct answer is A) Nature has supernatural powers.
