What does the prefix dactyl(o) refer to?

Explanation:
The prefix dactyl(o) refers to digits—the fingers and toes. It comes from a Greek root meaning finger or toe, and is used in terms that talk about digits in general, such as polydactyly (extra digits) or dactylitis (inflammation of a digit). Nails and the palm are different parts of the hand, so they aren’t what this prefix denotes. Therefore, the best choice is the one that means finger or toes.
