A metaphor is another way of saying something, for example from Guardians of the Galaxy. Quill mentions Drax with this metaphor:
"I'm going to have to agree with the thesaurus on that one." That is basically a metaphor.
I'm pretty sure it is C. The reasons being that the poem is called "We Wear the Mask". That means that they are showing one thing on the outside, but are saying something different on the inside. Like they are pretending. C makes the most sense because the passage states that they smile on the outside but their souls are crying.
