Fibrous proteins, such as collagen and keratin, tend to be elongated and have a repetitive structure that makes them insoluble in water. On the other hand, globular proteins, such as enzymes and antibodies, have a more folded, compact structure and are generally soluble in water. Therefore, choice C is the correct statement.
