What is the best reason to use a complete sentence to introduce a direct quote?
(A) to prove to readers that you understand what the direct quote means
(B)to set text apart from other parts of an essay as a block quotation
(C)to indicate that the direct quote is needed as part of your argument
(D)to provide some background information about the quote or speaker

(D)to provide some background information about the quote or speaker

Explanation:

Whenever quoting from a direct source, it is necessary to frame the quote. Don't just drop it like a bomb without providing background information: how does the audience know it's a source they can trust? If you know the author, context, situation, you should include those details.

The other answers don't work as well: you're not "proving" anything; you can use a block quotation, but I think personally that those are tacky; the direct quote isn't "needed" in your argument, because you could probably make do without it.

a is your answer
