How many chromosomes are found in human body cells?

The correct answer is: 46

Human body cells have 23 pairs of chromosomes, for a total of 46 chromosomes. This includes 22 pairs of autosomes and 1 pair of sex chromosomes (XX for females and XY for males). Option A (23) is incorrect because that is the number of chromosomes in a single human reproductive cell (egg or sperm). Option B (16) is incorrect because it is not a multiple of 23 and there are not 16 pairs of chromosomes in human body cells. Option D (13) is incorrect because it is not a multiple of 23 and there are not 13 pairs of chromosomes in human body cells. Therefore, the correct answer is C (46).
