Which of these is an example of binary fission?

Binary fission is a type of asexual reproduction in which a single organism divides into two equal parts, each with the potential to grow into a fully mature individual. It is a common form of reproduction in unicellular organisms.

Out of the given options, Amoeba sp. is an example of binary fission. During binary fission, the nucleus of the parent cell divides, followed by the division of the cytoplasm, resulting in the formation of two new daughter cells.

Plants reproduce through sexual or asexual means, depending on the species. They do not undergo binary fission. Similarly, elephants and humans reproduce sexually, making them irrelevant to the concept of binary fission.

Therefore, the correct answer is Amoeba sp.
