The correct option is B binary fission
The most common method of bacterial reproduction is binary fission. Binary fission takes place by amitosis. In binary fission, the parent cell divides and forms two daughter individuals.
Sexual reproduction is absent in bacteria. However, there is a process that is comparable to sexual reproduction or we can say a primitive form of sexual reproduction, wherein the exchange of DNA (genes) takes place. It is known as bacterial recombination. It occurs in three ways: conjugation, transduction and transformation.
