D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the position of the testes in whales. We need to determine whether they are located externally, internally, or in some other configuration.

2. **General Information about Testes in Mammals:**
In most mammals, including humans, the testes are located in a scrotal sac which is situated beneath the penis. This allows for temperature regulation, which is crucial for sperm production.

3. **Specific Information about Whales:**
Whales are unique among mammals in that their testes are not located in a scrotal sac. Instead, they are found internally within the body. This is an adaptation to their aquatic environment.

4. **Comparison with Other Animals:**
Similar to whales, other large mammals like elephants, dolphins, and rhinoceroses also have their testes located internally. This is a common trait among certain large mammals.

5. **Analyzing the Options:**
- **Extra abdominal:** This is incorrect as the testes are not located outside the abdomen.
- **Half external and half internal:** This is also incorrect since the testes are completely internal in whales.
- **Internal:** This is correct as we have established that whale testes are located internally.
- **None of the above:** This is incorrect since we have identified the correct option.

6. **Conclusion:**
The correct answer is that the testes in whales are internal.

**Final Answer:**
The testes in whales are internal.
