Answer:

The correct answer would be meiosis.

In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.

It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.

The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.

Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.

In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.

The process of sexual reproduction involves two parents contributing one gamete each. Gametes are produced by the process meiosis in which exchange of chromosomes happen causing genetic variation. Good luck!

<h2>Answer:</h2>

<u>B. Spores</u> are involved in both sexual and asexual reproduction.

<h2>Explanation:</h2>

In science, a spore is a unit of sexual as well as asexual proliferation that might be adjusted for dispersal and for endurance, frequently for expanded timeframes, in troublesome conditions.

Bacterial spores are not part of a sexual cycle but rather are safe structures utilized for endurance under horrible conditions. Under good conditions, the spore can form into another living being utilizing mitotic division, delivering a multicellular gametophyte, which inevitably proceeds to create gametes.
