Consider the following statements (A-C) each with one or two blanks.
(A) `underline((1))` are the most abundant cells (60-65 percent) of the total WBCs and `underline((2))` are the least (0.5-1 percent) among them
(B) Platelets are cell fragments produced from `underline((3))`
(C) During clot formation, fibrins are formed by the conversion of inactive `underline((4))` in the plasma by the enzyme `underline((5))`
Which one of the following options, gives the correct fill ups for the respective blank numbers from (1) to (5) in the statements ?

Options

A. (1)-Neutrophils, (2)-basophils, (4)-fibrinogens, (5)-thrombin
B. (3)-mast cells, (4)-thrombokinase, (5)-prothrombin
C. (3)-megakaryocytes, (4)-prothrombin, (5)-thrombin
D. (1)-Basophils, (2)-neutrophils, (3)-reticulocytes

Answer

A

Explanation

Blood platelets are cell fragments rather than true cells, they are formed from megakaryocytes (very large cells of bone marrow).
