Best answer

Answer: 3. Antigen binding site is located at C-terminal region of antibody molecules.

Key idea: An antibody is Y-shaped, made of 2 heavy and 2 light chains joined by disulfide bonds.

Statements 1, 2 and 4 are correct. The constant regions lie at the C-terminal end. The antigen-binding site is at the N-terminal (variable) region, so statement 3 is wrong. Option 3.
