The selection of medium (written version vs. visual image) mostly affects the understanding of a theme.

Hey there!
We know that a metaphor is a form of figurative language. Its purpose is to compare two things without using the words "like" or "as", because that would make it a simile.
That allows us to rule out A and D.
Since you asked for which best identifies as the best metaphor, I'm going to go with C. It provides a better and more clear comparison as opposed to B.
Hopefully this helps!
