The correct option is A Asexual reproduction is common among multicellular organisms.
Asexual reproduction is common among single-celled organisms and in plants and animals with relatively simple organisations.
In asexual reprodution, a single parent is involved in producing offspring. As a result, the offspring that are produced are not only identical to one another but are also exact copies of their parents. These offspring are morphologically and genetically identical to one another. The term clone is used to describe such morphologically and genetically similar individuals. Binary fission is a type of asexual reproduction. In binary fission a parent cell divides into two daughter cells of approximately equal size and each rapidly grows into an adult. Example: Amoeba, Paramecium.
