Here's why it's the answer and why the other options are incorrect:
* Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It results in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This reduction is essential for maintaining the correct chromosome number in offspring.
* Molds, ferns, insects, bacteria, and protozoans are all diverse groups of organisms. While some of them reproduce sexually, many also reproduce asexually.
* Molds, ferns, and insects can reproduce both sexually and asexually.
* Bacteria and protozoans primarily reproduce asexually.
Since meiosis is a process specifically involved in sexual reproduction, it is not necessarily a part of the life cycle for all organisms.
