Options

A. 10 and 20
B. 10 and 10
C. 20 and 10
D. 20 and 20

Answer

To determine the number of cranial nerves and spinal nerves in a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Nervous System**:
- The frog has a complex nervous system that includes both cranial and spinal nerves. The nervous system is responsible for controlling voluntary and involuntary activities in the body.

2. **Cranial Nerves**:
- Frogs possess a total of **10 pairs of cranial nerves**. These nerves are primarily responsible for transmitting sensory information from the environment to the brain, which includes functions such as smell, hearing, and sight.

3. **Spinal Nerves**:
- Similarly, frogs also have **10 pairs of spinal nerves**. These nerves are responsible for carrying information from various organs in the body back to the brain, facilitating communication within the nervous system.

4. **Conclusion**:
- Therefore, the total number of cranial nerves in frogs is 10 pairs, and the total number of spinal nerves is also 10 pairs.

### Final Answer:
The number of cranial nerves and spinal nerves in a frog is **10 pairs of cranial nerves and 10 pairs of spinal nerves**.
