alleryDuring a bacterial or viral infection, one type of agranulocyte responds by producing antibodies. Which white blood cell is this?
AMonocyte
BNeutrophil
CEosinophil
DLymphocyte
Answer & Solution
Correct answer: D. Lymphocyte
1. The cell is an agranulocyte that makes antibodies during infection.
2. Neutrophils and eosinophils are granulocytes, ruling out options B and C.
3. Monocytes are agranulocytes but are phagocytic, not antibody makers, so option A is out.
4. The antibody-producing agranulocyte is the lymphocyte, option D.
