• B. 48
• C. 23
• D. 46

Answer: (D)

Verified step by step guidance

1. Understand that humans are diploid organisms, meaning they have two sets of chromosomes—one set inherited from each parent.
2. Recall that the haploid number (n) for humans is 23, which represents the number of chromosomes in a gamete (sperm or egg).
3. Since diploid cells contain two sets of chromosomes, calculate the total number of chromosomes by multiplying the haploid number by 2.
4. Express this calculation as an equation: \(\text{Total chromosomes} = 2 \times 23\).
5. Conclude that the total number of chromosomes in a diploid human cell is the result of this multiplication.
