Which sentence is best categorized as an analogy?

You didn't list options, but i think maybe you meant those options:

a. The look she gave her was as frigid as a winter wind.

b. He answered the questionnaire like a monkey with a typewriter

c. The old man who walked into the room, looked as tough as old boots

d. The words her friend spoke to her were as sweet as honey.

i think the best answer is b; ) it is no mere comparison, but a trasfer of meaning from how the monkey behaved (carelessly) to the person filling in the questionaire
