Ans. Option (a).
Binary fission is a characteristics of simple, prokaryotic organisms that belong to kingdom bacteria. It represents a type of asexual reproduction, which involves division of a parent cell to produce two daughter cells, with same genetic makeup as present in parent cell.
Binary division is similar to mitosis, which occurs in eukaryotic organisms for growth and development as both the processes involve replication of DNA and formation of two daughter cells from a parent cell.
Thus, the correct answer is option (a).
