Explanation:

Animal proteins typically contain all essential amino acids in sufficient amounts, making them complete proteins. Plant proteins often lack one or more essential amino acids (or have them in insufficient quantities), so they are incomplete. Thus, the correct pairing is animal proteins as complete and plant proteins as incomplete.

Answer:

A. complete, incomplete
