D
46
Verified step by step guidance1
Understand that humans have a diploid number of chromosomes, which is 46. This means each somatic (body) cell contains 46 chromosomes arranged in 23 pairs.
Recall that meiosis is a special type of cell division that reduces the chromosome number by half to produce gametes (sperm or egg cells).
During meiosis, the chromosome number is halved from diploid (2n) to haploid (n), so each resulting cell contains only one set of chromosomes.
Since the diploid number in humans is 46, the haploid number after meiosis is calculated as \(\frac{46}{2} = 23\) chromosomes per cell.
Therefore, each of the four cells produced by meiosis in humans contains 23 chromosomes.
