The correct option is D Anemia
Lead poisoning can lead to fatal diseases one including anaemia. Lead inhibits certain enzymes required for the synthesis of heme molecule. Heme is an integral part of haemoglobin of the RBCs. It carries oxygen in the body and provides to the cells for aerobic respiration. Lead poisoning indirectly leads to the loss of oxygen-carrying capacity of the RBCs and in turn can be fatal. So, the correct answer is option D.
