In which of the following organisms, multiple fission is a means of asexual reproduction?
options
- Yeast
- Leishmania
- Paramoecium

Answer
Plasmodium
Reason — Multiple fission is a type of asexual reproduction in which the parent cell divides into many daughter cells at the same time which occurs in Plasmodium, the parasite that causes malaria.
Inside its host’s liver or red blood cells, Plasmodium’s nucleus divides several times before the cell splits into many smaller cells, each forming a new organism.
