Right answer is (b) in the oxygen carrying capacity of blood
To explain: Anaemia is a reduction in the oxygen carrying capacity of the blood. It can develop from a change in the number, volume or Hb concentration of erythrocytes, caused by bone marrow dysfunction resulting in the poor production rate of RBCs. Since these changes are specific, the measurement of packed cell volume (PCV), the number of RBCs and the haemoglobin (Hb) are very important.
