best_answer

Antibodies have two regions:
→ Variable region (V region) → at the N-terminal, this part binds to the antigen.
→ Constant region (C region) → at the C-terminal, this part decides the antibody’s class and function.

So, the antigen-binding site is at the N-terminal, not at the C-terminal.

Hence, option (4) is correct.
