Which of the following is an example of an organism that reproduces via binary fission?

Binary fission is a form of asexual reproduction commonly found in prokaryotic organisms like bacteria, as well as some single-celled eukaryotes such as amoebas. In binary fission, an organism duplicates its genetic material and divides into two identical daughter cells. This process allows for quick population growth under favorable conditions.

In the case of the amoeba, it reproduces by this method, dividing its cytoplasm and genetic material evenly between the newly formed cells. This mode of reproduction is efficient and enables amoebas to rapidly increase their numbers in suitable environments.

The other organisms listed—dogs, fungi, and cats—do not reproduce through binary fission. Dogs and cats are multicellular organisms that reproduce sexually. While certain fungi can reproduce asexually, they typically do so through methods like budding or spore formation, rather than binary fission. Fungi can exhibit diverse reproductive strategies, but binary fission is not one of them.
