Options

A. Seprating nostrils form eyes
B. Keeping head out water while swimming
C. Increasing gape
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the function of the prolonged head forming a snout in members of the Crocodylia order (crocodiles).

2. **Analyzing the Options**:
- **Option A**: "Separating nostrils from eyes" - This suggests that the snout's function is to create a distance between the nostrils and the eyes.
- **Option B**: "Keeping head out of water while swimming" - This implies that the snout helps in maintaining the head's position above water during swimming.
- **Option C**: "Increasing gape" - This means that the snout allows for a larger mouth opening, which is useful for catching and consuming prey.
- **Option D**: "None of the above" - This indicates that none of the previous options are correct.

3. **Evaluating Each Option**:
- **Option A**: This is incorrect because crocodiles often keep their heads above water, making the separation of nostrils from eyes unnecessary.
- **Option B**: This is also incorrect as the function of keeping the head out of water is primarily due to the neck, not the snout.
- **Option C**: This is correct because a blunt snout allows crocodiles to open their mouths wider, which is essential for catching and consuming larger prey.
- **Option D**: This is incorrect since we have identified that Option C is a valid reason.

4. **Conclusion**: After evaluating all options, the correct answer is **C: Increasing gape**. This is the primary function of the prolonged snout in crocodiles, aiding them in capturing and eating their prey effectively.
