Correct answer: B

Option (b) is the correct answer as a healthy adult man has, on an average, 5 millions to 5.5 millions of RBCs (erythrocytes) mm–3 of blood.

Blood normally contains 1,50,000 – 3,50,000 platelets mm–3.

Neutrophils form 60-65 percent of the total WBCs, monocytes form 6-8 percent of the total WBCs and eosinophils form 2-3 percent of the total WBCs. The total WBCs are approximately 6000-8000 mm–3 of blood.

Thus, the formed elements in the decreasing order of their abundance in blood in humans: -

Erythrocytes – Platelets – Neutrophils – Monocytes – Eosinophils
