Answer:
The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.
Explanation:
The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).
Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.

The answer is <span>B. meiosis.
All cells in an organism are diploid (2n). Only reproductive cells are haploid cells (n). Mitosis is a division of a cell into two daughter cells identical to the mother cell. Meiosis is a cell division during which the number of chromosomes is reduced by half (from 2n to n). So, reproductive cells (n) are created by meiosis.
Cytokinesis is the phase during mitosis and meiosis.</span>
