Answer 1

A) quotations marks

Tip: I'm not sure if that's what your school does, but mine does. I normally do Quotations and italics. 

Answer 2

C. Underlined, although you should use italics (instead of underlining) for titles of larger works (books, magazines) and quotation marks for titles of shorter works (poems, articles).
