Respuesta :

Answer:

Option (A).

Explanation:

Haptens may be defined as incomplete antigen that are not capable of inducing an immune response.

Hapten is a small molecule that reacts with specific antibody but only generates an immune response when these are conjugated with the carriers or proteins. Penicillin is a hapten and generates an immune response when conjugated with the carrier molecule.

Thus, the correct answer is option (A).
