He used riddling to talk to Smaug I think because he wanted to stall and waste time as he figured out a plan. He also used riddles to talk to Golem who he clearly was trying to stall to save himself as Golem wanted to kill and eat Bilbo. So it is a reoccurring theme of Bilbo and it makes sense.
It's not B. It doesn't have quotation marks.
Not C because the first word in the quotations needs to be capitalized.
Not D because the quotation need to surround the statement.
So your answer is A :)
Hope this helped :)
Metaphors are used almost as much as personification in this passage, as the entire second stanza compares the mirror to a lake, but even before that metaphors are distinctly present. The mirror calls itself “the eye of a little god,” by that point in the poem, Plath has made sure that it’s clear that the mirror is distinguished as completely objective, “unmisted by love or dislike” and “not cruel, only truthful.”
