Which word set completes the following analogy?

knife : cut ::

A. dentist : teeth

B. hammer : nail

C. slice : strike

D. chop : axe

A knife cuts just as an axe chops.

Although dentist and teeth are related, a dentist does not teeth, teeth is not a verb.

Slice and strike are both verbs, so you can eliminate that.

A hammer doesn't really nail, they are both nouns.

So the answer is, I believe, D. chop : axe.
