Which organ is oval in shape , has a dense covering lies in extra-abdominal pouch having two 2 to `2.5^@C` lower temperature than the body is ?

Options

A. Ovary
B. Eyeball
C. Testis
D. Epididymis

Answer

To solve the question, we need to identify the organ that meets the following criteria:

1. **Shape**: The organ must be oval in shape.
2. **Covering**: It must have a dense covering.
3. **Location**: It should lie in an extra-abdominal pouch.
4. **Temperature**: The organ must have a temperature that is 2 to 2.5 degrees Celsius lower than the body temperature.

### Step-by-Step Solution:

**Step 1: Analyze the options provided.**
- We need to consider each option carefully to see if they meet the criteria listed above.

**Step 2: Evaluate Option 1 - Ovary.**
- The ovary is indeed oval in shape, but it is located within the abdominal cavity, not in an extra-abdominal pouch. Therefore, this option does not meet all the criteria.

**Step 3: Evaluate Option 2 - Eyeball.**
- The eyeball is not typically described as oval in shape (it is more spherical) and is not located in an extra-abdominal pouch. Thus, this option is also incorrect.

**Step 4: Evaluate Option 3 - Testes.**
- The testes are oval in shape and have a dense covering (tunica albuginea). They are located in the scrotum, which is an extra-abdominal pouch. Additionally, the temperature in the scrotum is indeed 2 to 2.5 degrees Celsius lower than the normal body temperature, which is crucial for sperm production. Therefore, this option satisfies all the conditions.

**Step 5: Evaluate Option 4 - Epididymis.**
- The epididymis is associated with the testes and is not an organ on its own that meets the criteria. It does not have a distinct shape or function that fits the description given in the question.

**Conclusion:**
- Based on the evaluations, the correct answer is **Option 3 - Testes**.
