C. Unique three-dimensional shape of the fully folded polypeptide

The tertiary structure of a protein is the unique three-dimensional shape of the fully folded polypeptide

Explanation;

A protein is a functional biological molecule that is made up of one or more polypeptides that are folded/coiled into a specific structure.

Tertiary structure results from the interactions between the side chains (R groups) of the various amino acids.
