Answer:
The correct answer will be option A (mitosis, part of asexual reproduction because it produces diploids).
Step-by-step explanation:
Asexual reproduction is a way of reproduction which produces cells with the same genetic material called "clones". Asexual mode of reproduction dominates in simple unicellular organisms such as bacteria and some protozoa to a complex organism like plants which uses it to spread in altitudes.
Since mitosis is a type of equational cell division which produces two daughter cells with the same number of chromosomes or ploidy level from single parent cells. This method of cell division is used in producing clones with same genetic material in asexual reproduction.
thus, option A is the correct answer.
