Two main types of cell division cell division are mitosis and meiosis. Meiosis is the process of cell division in which a single cell divides into the four daughter cells. This division is also known as reduction division.
The meiosis takes place in the gamete or sex cell. Sperm and ova are produced by reducing the chromosome number upto the half so that zygote can restore the diploidy. Hence, sperm cells are produced by the process of meiosis.
Today in Biology my teacher discussed about Meiosis & sperm cells the other choices were not involved. I would choose that one as it being a reproductive cell.
