Answer Choice D

^^^ I would also love an explanation as I'm confused on this as well.

Hi Sallyanne and Nishant, I don't think that the trickster is actually used for social commentary, but rather that character type serves to instruct listeners about how to act.We see this in the last sentence of the third paragraph, which tells us that trickster's role is to help the listener avoid their flaws. Rather, it is the picaro who is used for social commentary, holding a mirror to a corrupt society. From the context, C looks good. The main point of this paragraph is to show the difference between the picaro and the trickster.
