  1. 15,000 - 35,000 per mm3
  2. 1,500,000 - 3,500,000 per mm3
  3. 150,000 - 350,000 per mm3
  4. 5,000 - 10,000 per mm3
Show answer and explanation

Correct answer: 150,000 - 350,000 per mm3

Blood normally contains between 1,50,000 and 3,50,000 platelets per cubic millimeter. A significant reduction in this count can lead to clotting disorders and excessive blood loss.
