A. Abdominal cavity
B. Thoracic cavity
C. Extra-abdominal cavity
D. Pericardial cavity

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the location of the testes in mammals.

2. **Understand the Function of Testes**: The testes are male reproductive organs responsible for producing male gametes (sperms) through a process called spermatogenesis.

3. **Determine the Location of Testes**:
- The testes are not located in the abdominal cavity; they are positioned outside of it.
- They are specifically located in a pouch called the scrotum.

4. **Purpose of the Location**: The scrotum helps maintain a lower temperature than the body’s core temperature, which is essential for the proper production of sperm.

5. **Evaluate the Options**:
- **Abdominal cavity**: Incorrect, as the testes are outside this cavity.
- **Thoracic cavity**: Incorrect, as this cavity is located in the chest area.
- **Extra abdominal cavity**: Correct, as this refers to the location outside the abdominal cavity where the testes are found.
- **Pericardial cavity**: Incorrect, as this cavity surrounds the heart.

6. **Conclusion**: The correct answer is that the testes are located in the extra abdominal cavity (specifically in the scrotum).

**Final Answer**: The testes in mammals are located in the extra abdominal cavity.
