Answer:
I would say that the sentence that best analyses the poets use of allusion in this passage from The Lovesong of J. Alfred Prufrock is A: The speakers refers to Michelangelo to show how people pretend to be who they're not so they can fit in.
Explanation:
An allusion in literature occurs when the writer makes a reference to a person, place, thing or idea of historical, cultural, literary or political significance to try to explain better what he/she wants to express. In this case, the writer refers to Michelangelo in order to describe people who pretend to be -or to know- about cultural stuff. These people try to show themselves as experts in art by talking about Michelangelo just to fit in.
