Diploid chromosome number in humans is :

Options

A. 46
B. 44
C. 48
D. 42

Explanation

To determine the diploid chromosome number in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosome Number**:
- Chromosomes exist in pairs in diploid organisms. The diploid number (2n) represents the total number of chromosomes, which includes both sets from each parent.

2. **Identifying the Haploid Number**:
- The haploid number (n) is the number of chromosomes in a gamete (sperm or egg). In humans, the haploid number is 23.

3. **Calculating the Diploid Number**:
- To find the diploid number, we multiply the haploid number by 2:
\[ 2n = 2 \times n = 2 \times 23 = 46 \]

4. **Conclusion**:
- Therefore, the diploid chromosome number in humans is 46.

### Final Answer:
The diploid chromosome number in humans is **46**.
