The type of immunity provided by the molecule shown in the diagram:

The correct answer is Option (1) → Humoral

Option (1) Humoral — Correct. The antibodies are found in the blood, so the response is antibody-mediated.

Option (2) Cell mediated — Incorrect. Cell-mediated immunity is carried out by T-lymphocytes themselves, without antibodies; it causes, for example, graft rejection.

Option (3) Innate immunity — Incorrect. Innate immunity is present from birth and is non-specific: skin, acid, saliva, phagocytes and interferons. Antibodies belong to acquired immunity.

Option (4) Both humoral and cell mediated — Incorrect. Antibodies give only the humoral response.

NCERT Extract:
Acquired Immunity – “… Because these antibodies are found in the blood, the response is also called as humoral immune response. This is one of the two types of our acquired immune response – antibody mediated. The second type is called cell-mediated immune response or cell-mediated immunity (CMI). The T-lymphocytes mediate CMI.”
