Answer
The correct answer is **(c) meiosis**. Here's why:* **Meiosis** is a type of cell division that specifically occurs in the production of gametes (sex cells like sperm and egg). The goal of meiosis is to reduce the number of chromosomes in the parent cell by half, ensuring that when two gametes combine during fertilization, the offspring has the correct number of chromosomes.Let's look at why the other options are incorrect:* **Cytokinesis** is the process of dividing the cytoplasm of a cell after mitosis or meiosis. It doesn't change the amount of DNA.* **Binary fission** is a form of asexual reproduction used by single-celled organisms like bacteria. It results in two identical daughter cells, each with the same amount of DNA as the parent cell.* **Mitosis** is a type of cell division that produces two identical daughter cells, each with the same amount of DNA as the parent cell.* **Cell fusion** is a process where two cells combine to form a single cell. This doesn't necessarily change the amount of DNA. **In summary:** Meiosis is the only cell division process that reduces the amount of DNA in the daughter cells compared to the parent cell.
