Answer:
The correct answer is option D-it is used primarily by prokaryotes for asexual reproduction.
Step-by-step explanation:
Mitosis is a type of cell division which is used by the organism which reproduces through the asexual mode of reproduction.
Binary fission is also a type of asexual reproduction which is common among prokaryotes like bacteria, archaea and protists where a cell divides producing two daughter cells.
But these both modes of asexual reproduction have a difference as mitosis is present in higher multicellular organisms also along with few lower organism whereas binary fission is present in prokaryotes only.
Thus, option D-it is used primarily by prokaryotes for asexual reproduction is the correct answer.
