Question

Study the diagram given below and identify the cells labelled as A, B, C and D, and choose the correct option.

• A. A = Eosinophil, B = Erythrocyte, C = Neutrophil and D = Basophil
• B. A = Eosinophil, B = Lymphocyte, C = Neutrophil and D = Monocyte
• C. A = Erythrocyte, B = Basophil, C = Neutrophil and D = Lymphocyte
• D. A = Eosinophil, B = Monocyte, C = Neutrophil and D = Lymphocyte

Answer 1

Answer: (D)

A = Eosinophil, B = Monocyte, C = Neutrophil and D = Lymphocyte

• The diagram shows the different types of blood cells.
• The label A refers to eosinophils. The nucleus of these cells is bilobed. They are involved in allergic and inflammatory reactions.
• The label B refers to monocytes. They have a kidney-shaped nucleus.
• The label C refers to neutrophils. They have a multilobed nucleus. the monocytes and neutrophils are involved in phagocytosis. The label D refers to lymphocyte. They have a large circular nucleus. They form the immune T cells and B cells.

Thus, the correct answer is option D.
