A
It helps to transport oxygen.
💡 Explanation:
  •  Iron is an essential element for blood production. 
  • About 70 per cent of your body's iron is found in the red blood cells of your blood called haemoglobin and in muscle cells called myoglobin.
  •  Haemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Hence, the role of iron in the blood is that it helps to transport oxygen. 
So, the correct answer is 'It helps to transport oxygen'.
