Final answer:
The Red Book is the reference guide that lists biological products licensed by the FDA; therefore, the correct option for the student's question is option C.
Step-by-step explanation:
The reference book that primarily lists biological products, including any biosimilar and interchangeable biological product licensed by the Food and Drug Administration (FDA), is the Red Book.
The Physicians' Desk Reference (PDR) is often used by medical professionals to find information primarily about prescription drugs, while the Orange Book lists approved drug products with therapeutic equivalence evaluations. As for the Handbook of Nonprescription Drugs, it provides information on over-the-counter drug products. Since biological products are listed in the Red Book, option C is the correct option.
