Which statement correctly defines incomplete proteins?

Explanation:
Incomplete proteins are those that do not supply all of the essential amino acids in adequate amounts. Since nine essential amino acids must come from the diet, a protein is considered incomplete if it lacks one or more of these amino acids (or provides them in insufficient amounts). Many plant-based foods fall into this category, which is why combining different plant proteins (complementary proteins) can provide a complete amino acid pattern. In contrast, a complete protein contains all nine essential amino acids in sufficient amounts.
