What is the correct relation between the chromosome number in a human body cell and that in a reproductive cell?

Answer and explanation

Correct answer: A body cell has 46 and a reproductive cell has 23

Human somatic, or body, cells are diploid and normally contain 46 chromosomes arranged in 23 pairs. Human reproductive cells, or gametes, are haploid and contain 23 chromosomes, one from each pair. This reduced number allows sperm and egg to fuse and restore 46 chromosomes in the zygote. Therefore option B is correct; options A, C and D contradict the normal human chromosome counts.
