Aquatic reptiles are

Options

A. ammonotelic
B. ureotelic
C. ureotelic in water
D. ureotelic over land

Explanation

**Step-by-Step Solution:**

1. **Understanding Aquatic Reptiles**: Aquatic reptiles are reptiles that primarily live in water. Examples include turtles and alligators.

2. **Excretory Products**: The type of excretory product an organism produces is influenced by the availability of water in their environment.

3. **Types of Excretory Products**:
- **Ammonotelic**: Organisms that excrete ammonia. This is common in aquatic animals that have access to abundant water, as ammonia is highly toxic and requires a lot of water to be safely excreted.
- **Ureotelic**: Organisms that excrete urea. This is seen in semi-aquatic animals and some land animals where water availability is moderate.
- **Uricotelic**: Organisms that excrete uric acid. This is typical for many terrestrial reptiles and birds, especially those in arid environments, as uric acid requires less water to excrete.

4. **Identifying the Excretory Product of Aquatic Reptiles**: Since aquatic reptiles like turtles and alligators live in water, they are classified as ureotelic. They excrete urea, which requires a moderate amount of water for excretion.

5. **Evaluating the Options**:
- **Option 1: Ammonotelic** - Incorrect, as aquatic reptiles do not excrete ammonia.
- **Option 2: Ureotelic** - Correct, as aquatic reptiles excrete urea.
- **Option 3: Ureotelic in water and over land** - Incorrect, as they are consistently ureotelic regardless of their environment.

6. **Conclusion**: The correct answer is that aquatic reptiles are ureotelic.

**Final Answer**: Aquatic reptiles are ureotelic (Option 2).
