• B. 23
• C. 22
• D. 44

Answer: (B)

Verified step by step guidance

1. Understand that the haploid number refers to the number of chromosomes in a gamete (sperm or egg), which contains only one set of chromosomes.
2. Recall that humans are diploid organisms, meaning their somatic cells have two sets of chromosomes, one from each parent.
3. Know that the diploid number of chromosomes in humans is 46, which represents two complete sets.
4. To find the haploid number, divide the diploid number by 2, since haploid cells have half the number of chromosomes.
5. Express this mathematically as: \(\text{haploid number} = \frac{\text{diploid number}}{2} = \frac{46}{2}\).
