In multicellular organisms, the formation of sperm and egg cells, also known as gametes, occurs through a specialized type of cell division called meiosis. Meiosis involves two rounds of division, resulting in four genetically diverse daughter cells, each with half the number of chromosomes as the parent cell. Therefore, option B is correct, which states that meiosis results in the formation of sperm and egg cells. In contrast, mitosis is the type of cell division that results in the formation of two identical daughter cells with the same number of chromosomes as the parent cell. Binary fission is a type of cell division that occurs in prokaryotes, while cytokinesis is the physical separation of the cytoplasm during cell division.
