• A. Lymphocytes
• B. Basophils
• C. Erythrocytes
• D. Monocytes

Answer 1

The correct option is D Monocytes

Monocytes are the largest corpuscles of mammalian blood. They are agranulocytes i.e. agranular white blood cells because they do not contain granules. They have horse-shoe shaped or reniform nucleus. They are actively motile and phagocytic cells which are formed in bone marrow. They regulate immunity of body against foreign pathogens or substances. They make up 2-7% of total leucocytes count which is about 200- 700 cells/mm³ of blood.

So, the correct answer is 'Monocytes'.
