B
Meiosis
C
Osmosis
D
Transcription
Explanation: 

Detailed explanation-1: -In meiosis, a single cell divides twice to produce four daughter cells. These daughter cells or sex cells have exactly half the genetic material of normal gametes. Meiosis necessitates two divisions since it produces a haploid cell with half the amount of chromosomes. Thus meiosis occurs twice.

Detailed explanation-2: -That means there is a prophase I and a prophase 2.

Detailed explanation-3: -Meiosis does PMAT twice! That means there is a prophase I and a prophase II. There is a metaphase I and a metaphase II.

Detailed explanation-4: -Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice-once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

Detailed explanation-5: -Metaphase 2-chromosome lines up in middle but are not in pairs. Meiosis goes through PMAT twice!
