Options

A. 1 pair
B. 10 pairs
C. 23 pairs
D. 46 pairs

Answer

To answer the question "How many pairs of chromosomes are present in a single cell of the human body?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosomes**: In humans, each cell contains chromosomes that carry genetic information.

2. **Total Number of Chromosomes**: A typical human cell has a total of 46 chromosomes.

3. **Pairs of Chromosomes**: Since chromosomes come in pairs, we need to determine how many pairs there are in the total of 46 chromosomes.

4. **Calculating Pairs**: To find the number of pairs, we divide the total number of chromosomes by 2:
\[ \text{Number of pairs} = \frac{46 \text{ chromosomes}}{2} = 23 \text{ pairs} \]

5. **Conclusion**: Therefore, in a single cell of the human body, there are 23 pairs of chromosomes.

### Final Answer:
The number of pairs of chromosomes present in a single cell of the human body is **23 pairs**.
