How many chromosomes are in a human sperm cell?

Explanation:
Gametes are haploid, carrying half the usual chromosome number, which is set up so fertilization restores the full set. In humans, body cells have 46 chromosomes (23 pairs), so a sperm cell contains 23 chromosomes: 22 autosomes plus one sex chromosome (X or Y). This arrangement allows fertilization with an egg, which also contributes 23 chromosomes, to produce a 46-chromosome zigote. The other options don’t fit because 46 is the diploid count for body cells, 22 would miss the sex chromosome, and 24 would exceed the haploid set.
