Explanation:

Theropods are a group of dinosaurs and the development of feathers is related to genetic - level changes. Mutations in DNA can alter the normal development processes. Placodes are the embryonic structures related to feather development. A mutation in DNA that affects the placodes which control genes for feather - related development would best explain the development of feathers in some theropods.

Answer:

C. A mutation in DNA caused the placodes that control genes to grow feathers.
