• A. a precursor of hemoglobin
• B. a toxin from Streptococcus
• C. a toxin from Plasmodium species
• D. a toxin from Haemophilus species

Answer 1

The correct option is C

a toxin from Plasmodium species

Malaria is a deadly infectious disease caused by the intraerythrocytic protozoan parasite Plasmodium. Malaria infected red blood cells show the presence of malarial pigment called haemozoin. Haemozoin is a biocrystal synthesized by Plasmodium and other blood-feeding parasites to avoid the toxicity of free haeme derived from the digestion of haemoglobin during invasion of the erythrocytes.
