Match List I with List II and select the correct answer by using codes given below the lists: List I I. Vitamin A) Pepsin II. Enzyme B) Carotene III. Hormone C) Keratin IV. Protein D) Progesterone Codes:

The correct option is B based on the following associations between the lists: I. Vitamin matches with B (Carotene). Beta-carotene is a precursor to Vitamin A and is often classified within the vitamin group in this context. II. Enzyme matches with A (Pepsin). Pepsin is a primary digestive enzyme produced in the stomach that breaks down proteins into smaller peptides. III. Hormone matches with D (Progesterone). Progesterone is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle and pregnancy. IV. Protein matches with C (Keratin). Keratin is a structural fibrous protein that makes up hair, nails, and the outer layer of human skin. Matching these pairs leads to the sequence I-B, II-A, III-D, IV-C.
