Multiple fission occurs in A. Hydra B. Plasmodium C. PlanariaD. All of the above

Multiple fission is a form of reproduction where a single organism divides into multiple offspring simultaneously. Among the options you've provided, multiple fission occurs in:

B. Plasmodium

Plasmodium is a genus of parasites that cause malaria. During their life cycle, certain species of Plasmodium undergo a process called schizogony, which involves multiple fission. In this process, the parasite's nucleus undergoes multiple divisions without the cell itself dividing, resulting in the formation of multiple daughter cells within a single parent cell. These daughter cells then break out of the parent cell to continue the infection cycle.
