Paramecium reproduces asexually, by binary fission. Plasmodium: Plasmodium is a malarial parasite. It chooses multiple fission , because more daughter neuclei are formed. Amoeba : Amoeba reproduces primarily by binary fission. However, a method known as multiple fission is adopted by the unicellular organism Amoeba to survive and reproduce under unfavourable conditions Answer:(b)
