C Correct answer
Explanation

Valine is a hydrophobic amino acid, making it likely to be buried in the interior of water-soluble globular proteins to avoid contact with water. Aspartate and Glutamate are negatively charged (hydrophilic) and prefer surface locations. Glycine is small and flexible but not specifically excluded from surfaces.
