Which one of the following statements best describes the role of B cells and T cells in the human body?

B.They alleviate the body's pain and inflammation.
A.They protect the body from environmental allergens.
C.They act as immunosuppressants in the body.
D.They protect the body from the diseases caused by pathogens.

Correct Answer: Option D

The human body's immunity is its ability to fight off diseases.

B-lymphocytes (B-cells) and T-lymphocytes (T-cells) are crucial components of acquired immunity.

B-cells are responsible for antibody-mediated immunity (humoral immunity).

T-cells are responsible for cell-mediated immunity.

Therefore, B cells and T cells protect the body from diseases caused by pathogens.

Hence, option (d) is the correct answer.
