Exo-erythrocytic schizogony in the life cycle of malarial parasite Plasmodium occurs in :
Answer: B
Exo-erythrocytic schizogony occurs in the Liver.
The sporozoites injected by the mosquito travel in the blood to the liver and enter hepatocytes. There they multiply asexually by schizogony, outside red cells (hence exo-erythrocytic), and release thousands of merozoites.
Only those merozoites then invade red blood cells and begin erythrocytic schizogony, which causes the fever. 'Blood' is too vague and is where the merozoites travel, and in the mosquito the stage is sporogony, with oocysts on the stomach wall, not schizogony.
