The correct answer is A. 23.
A human sperm cell contains half the number of chromosomes as a normal human cell, so it has 23 chromosomes. This is because during fertilization, when the sperm cell combines with an egg cell, the resulting zygote will have a complete set of 46 chromosomes, with 23 coming from the sperm cell and 23 coming from the egg cell.
