Humans have how many pairs of chromosomes?

Question

BlackTom AI · Accepted Answer

The question asks about the number of pairs of chromosomes in humans, which is a fundamental fact in human genetics. 
Option a: '46' — This is the total number of chromosomes in a human cell (23 pairs × 2), not the number of chromosome pairs. If someone confuses total chromosomes with pairs, they would select this by mistake. 
Option b: '12' — This value is far from the human chromosomal count and does not correspond to any standard chromosome pairing or haploid set; it reflects a misunderstanding of chromosome numbers. 
Option c: '15' — Similar to option b, this is not related to the human chromosome count and would indicate a misremembering of biology basics. 
Option d: '23' — This represents the correct count of chromosome pairs in humans. Humans have 23 pairs of chromosomes, totaling 46 chromosomes, with 22 autosome pairs and 1 sex chromosome pair. The distinction between 'pairs' and 'total chromosomes' is often the source of confusion, so recognizing that 23 is the number of pairs helps avoid conflating it with 46 total chromosomes. 
Overall, the reasoning hinges on correctly mapping the concept of 'pairs' to the numerical value and not conflating it with the total chromosome count.
