These lines of poetry from "Totally like whatever, you know?" are most likely stated as a question for what purpose?

"Invisible question marks and parenthetical (you know?)'s
have been attaching themselves to the ends of our sentences?"
a-To make fun of the manner of speaking that the writer is criticizing maybe
b- To show that questions are always appropriate x wrong
c-To emphasize the speaker's confusion maybe
d-To show that the speaker does not know how to use punctuation xwrong
