Answer:
A (24 chromosomes)
Explanation:
Meiosis is a kind of cell division that produces four daughter cells in which each of the cells have a reduced number of chromosome (by half) as the parent cell.
According to the question, the organism has 24 pairs of homologous chromosomes i.e. each pair of chromosome is from each parent. In total, the organism (diploid, 2n) has 48 chromosomes.
Meiosis occurs in two stages; meiosis I and meiosis II. In meiosis I, homologous chromosomes are pulled apart to opposite end of the cell at the anaphase stage. Hence, out of 48 chromosomes, 24 chromosomes are pulled to one end while the other 24 to the other end of the cell. The reduction in chromosome number occurs in meiosis I.
Meiosis II is quite similar to mitosis. Sister chromatids (duplicated chromosomes) are pulled apart to each cell in the anaphase of meiosis II. Each chromatids act as individual chromosomes in the daughter cells after division.
In a nutshell, after meiosis II, four haploid (n) daughter cells will be produced with each cell having 24 chromatids/chromosomes.
