D Correct answer
Explanation

When proteins are heated during cooking, their chemical structure unfolds in a process called denaturation. Following this, the unfolded protein chains bond together to form a solid or semi-solid structure, which is known as coagulation. Gelatinisation refers to starch, while convection and radiation are methods of heat transfer.
