Final answer:
Option (d), A human cell, apart from gametes, has 46 chromosomes, consisting of 23 pairs, and is diploid, with two sets of chromosomes. Gametes have only 23 chromosomes and are haploid.
Step-by-step explanation:
With the exception of gametes, a human cell contains 46 chromosomes. These chromosomes are arranged in 23 pairs, with each set of chromosomes being inherited from each parent. Human somatic cells, which include all cell types except gametes, are diploid, meaning they have two sets of chromosomes.
In contrast, gametes (sperm and egg cells) contain only 23 chromosomes, and are therefore haploid, having just a single set of chromosomes.
