Meiosis is best seen in

Answer: Option A

Meiosis is best seen in Gamete.
Meiosis means, 'lessening' since it is a reductional division is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
The organism's diploid germ-line stem cells undergo meiosis to create haploid gametes, which fertilize to form the zygote.
As a result, the production of gametes with half the number of chromosomes as the parent cell is the same.
