Options
- AA-II, B-I, C-III, D-IV
- BA-II, B-III, C-IV, D-I
- CA-II, B-I, C-IV, D-III
- DA-IV, B-I, C-II, D-III
Correct answer
C. A-II, B-I, C-IV, D-III
Step-by-step solution
According to NCERT, leucocytes are divided into two main categories: granulocytes and agranulocytes. Neutrophils are the most abundant cells ( 60 - 65 % ) of the total WBCs. Basophils are the least abundant ( 0.5 - 1 % ) among them. Monocytes constitute 6 - 8 % of total WBCs. Eosinophils constitute 2 - 3 % of total WBCs. Therefore, the correct matching is A-II, B-I, C-IV, D-III. Swapping the percentages of Monocytes and Eosinophils or Neutrophils and Monocytes leads to the incorrect options. Answer: A-II, B-I, C-IV
