Question 20 options:

A)

CD8 on the surface of cytotoxic T-cells

B)

CD4 on the surface of cytotoxic T-cells

C)

CD4 on the surface of helper T-cells

D)

CD8 on the surface of helper T-cells

Answer 1

Answer:

CD4 on the surface of helper T-cells.

Explanation:

MHC class II ( major histocompatibility complex) molecules are processed from the exogenous source. The presentation of  antigen on cells are important for the adaptive immune response.

MHC class II interact with CD 4 present on the surface of T helper cells. This interaction is important for the generation of an immune response. Helper T cells can release cytokines and can perform phagocytosis.

Thus, the correct answer is option (C).
