<reasoning>

Analyze cellular division outcomes

Meiosis involves two rounds of division to produce four genetically unique haploid gametes, which is essential for Sexual Reproduction. Mitosis produces two genetically identical diploid somatic cells. Thus, statement A is correct.

Evaluate reproduction types

Mitosis is the mechanism behind Asexual Reproduction in single-celled eukaryotes and somatic growth in multicellular organisms. Meiosis is strictly dedicated to sexual life cycles. Thus, statement B is correct.

Evaluate ploidy and variation

Statement C is incorrect because mitosis produces diploid cells, while meiosis produces haploid cells. Statement D is incorrect because meiosis, not mitosis, generates genetic variation through crossing over and independent assortment.
