Answer:
Binary fission
Step-by-step explanation:
Binary fission is a type of asexual reproduction in bacteria in which two identical daughter cells arise from a new cell. It is asexual in the sense that it does not require two parents but only one.
According to this question, Salmonella typhi is a bacteria that reproduces by splitting into two identical organisms. This is evidently a type of BINARY FISSION reproduction by the bacteria cell.
