Answer:
The correct answer is binary fission
Step-by-step explanation:
Prokaryotes or bacteria divide through an asexual mode of reproduction called "Binary fission".
The E.coli divides to produce genetically identical daughter cells which initiate when parent cell elongates which is replicated by the formation of the septum. After the formation of a septum, the cellular component is equally divided into the daughter cell along with the genome which moves to each side of the cell.
Thus, binary fission is the correct answer.
