What is the difference between b-cell lymphocytes and t-cell lymphocytes?
b cells regulate blood ph, and t cells regulate body temperature.
b cells are produced in the thymus, and t cells are produced in the bone marrow.
b cells engulf bacteria, and t cells carry bacteria to the lymph nodes.
b cells produce antibodies, and t cells destroy infected cells.

Ans.

B-cells or B-lymphocytes and T-cells or T-lymphocytes are components of adaptive immune system of body. Both these cells show specificity, diversity, memory, and ability to discriminate between self and non-self components.

The B-cells are antibodies-producing cells, against microbes or microbial components. These antibodies bind with the specific pathogens and neutralize them. The T-cells release various cytokines and immune molecules and destroy cells infected by pathogens or cancerous cells.

Thus, the correct answer is option). 'B cells produce antibodies, and T cells destroy infected cells.'

d is the answer

sorry if its wrong!
