Final answer:
Somatic cells are diploid and have 46 chromosomes, while gametes are haploid and have 23 chromosomes. Therefore, haploid cells have 23 strands without homologous/haploid pairs.
Step-by-step explanation:
Somatic cells are diploid, meaning they have two sets of chromosomes, while gametes are haploid, meaning they have only one set of chromosomes. So, the correct answer is d) Haploid cells because they have 23 strands without homologous/haploid pairs.
