Answer
23 pairs
Reason — Every cell of the human body has 46 chromosomes which occur in 23 pairs. 23 chromosomes are inherited from the mother. 23 chromosomes are inherited from the father. Together they form 23 pairs (46 chromosomes).
23 is the number of chromosomes in a human gamete. 46 pairs would mean 92 chromosomes, which is incorrect. Humans do not have 32 chromosomes.
