The correct option is D Formation of the contractile ring and transcription from chromosomes
Meiosis also called reductional division occurs only in reproductive cells for the formation of sex cells or gametes. It occurs in two stages - Meiosis I and Meiosis II. These two stages result in the formation of four haploid gametes. In Meiosis I, the diploid cell ( 23 pairs of chromosomes in humans) gives rise to two haploid cells (23 chromosomes each) i.e., each cell receives one chromosome (two sister chromatids) from each pair. In Meiosis II, each cell then divides to give rise to two cells with 23 chromosomes each. i.e. at the end of meiosis, we get four haploid cells.
Pairing of chromosomes occurs in mitosis.
