How Does Asexual Reproduction Work

How does asexual reproduction work?

A) In a single cell in any organism, the DNA is copied and the cell splits into two daughter cells, each with a complete copy of DNA, identical to the parent cell (except for any mutations) .
B) A single-celled organism splits into two cells, and an exact copy of the original DNA is generated within each daughter cell.
C) In a single-celled organism, the DNA is copied and the cell splits into two daughter cells, each with a complete copy of DNA, identical to the parent cell (except for any mutations) .
D) Two single-celled organisms combine such that each's DNA gets copied, and the daughter cells have DNA identical to the two parents except for any mutations.
E) In any organisms lacking specific genders, the DNA is copied within any parent cell and when the cell splits, each daughter cell gets an almost exact copy of the parent's DNA.
