There is a metaphor in B) She offered him a hundred-watt smile.

A metaphor is used to compare two unlikely things without using the words, like or as. Here, the woman's bright smile is being compared to a light bulb!

It would be B because it is comparing her smile to watts..Without using like or as. A metaphor is comparing two things without using like or as.
