Why can lack of haemoglobin cause tiredness in the body?

Answer and explanation

Correct answer: Because oxygen transport to body tissues may decrease

The governing concept is haemoglobin-mediated oxygen transport. Haemoglobin in red blood cells binds oxygen in the lungs and carries it to tissues. If haemoglobin is low, the blood may deliver less oxygen, so aerobic cellular respiration can produce less energy for normal activities; this may cause tiredness. Option A is correct, while B, C and D are unrelated.
