Which is an example of an extended metaphor?

Question

A. two lines in a poem that says an otter's eye looks like a black walnut.
B. an entire poem comparing a swimmer to a dolphin.
C. a line in a poem that says a man's voice is the boom of a baritone.
D. a poem that is about how the rain walks all over the city at different speeds.

Answer 1

B. an entire poem comparing a swimmer to a dolphin.

An extended metaphor involves a comparison that is developed throughout a piece of writing, rather than just in a single line or phrase. In this case, if the entire poem is comparing a swimmer to a dolphin, it qualifies as an extended metaphor.
