What is prominent in squatting position of Frog

Options

A. Bulging eyes
B. Tympanum
C. Hump
D. Unfolded fore limbs

Answer

To answer the question "What is prominent in the squatting position of a frog?", we will analyze each option provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding the Squatting Position**:
- The squatting position in frogs is characterized by their body posture where they bend their knees and hips, allowing them to sit back on their feet.

2. **Analyzing Option 1: Bulging Eyes**:
- Bulging eyes in frogs provide a wide field of vision (approximately 180 degrees) and help them see in various directions. However, they do not play a significant role in the squatting position itself. Therefore, this option is not correct.

3. **Analyzing Option 2: Tympanum**:
- The tympanum is an auditory structure that helps frogs hear both in air and underwater. While it is important for their sensory perception, it does not have a direct role in the squatting posture of frogs. Thus, this option is also incorrect.

4. **Analyzing Option 3: Hump**:
- The hump in the frog's body is prominent when it is in a squatting position. This hump bears the weight of the frog's body and is crucial for maintaining balance and posture. The weight is distributed on the feet, and the knees and hips are bent, which allows the frog to prepare for jumping. Hence, this option is correct.

5. **Analyzing Option 4: Unfolded Forelimbs**:
- The forelimbs of frogs are primarily used for jumping and controlling movement direction. While they are important for locomotion, they do not specifically contribute to the squatting position. Therefore, this option is incorrect.

### Conclusion:
From the analysis, the correct answer is **Option 3: Hump**, as it is the feature that is prominent in the squatting position of a frog.
