Answer:
The correct answer will be option-B
Step-by-step explanation:
Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.
Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.
The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.
Thus, Option-B is the correct answer.
