Answer:
b is the metaphor
Explanation:
the reasoning is because is simile makes a comparison to two things using the works like or as while a metaphor doesn't. an example of this is "she runs fast, LIKE a cheetah," that's a simile while "she's a cheetah running in the wind" is a metaphor, implying that she indeed is the cheetah not just fast like one when in reality she really isn't a cheetah at all. sorry if this is a little confusing.
