Uric acid of Sauropsides solid fies and found in

Options

A. Egg yolk
B. Egg shell
C. Egg membrane
D. Egg cytoplasm

Answer

### Step-by-Step Solution:

1. **Understanding the Context**: The question asks where uric acid is found in sauropsids, specifically in relation to their eggs. Sauropsids include reptiles and birds, which excrete nitrogenous waste in the form of uric acid.

2. **Identifying Uric Acid**: Uric acid is a type of nitrogenous waste that is excreted by certain organisms, including sauropsids. It is less toxic and conserves water, making it suitable for organisms that lay eggs.

3. **Analyzing the Options**: The options provided are:
- A) Egg yolk
- B) Egg shell
- C) Egg membrane
- D) Egg cytoplasm

4. **Evaluating Each Option**:
- **Egg Yolk**: The yolk serves as a nutrient source for the developing embryo. If uric acid were present here, it could harm the embryo, so this option is unlikely.
- **Egg Shell**: The shell provides protection and prevents desiccation. Uric acid can be deposited here as a waste product, making this a strong candidate.
- **Egg Membrane**: This layer also protects the egg but is not typically a site for waste accumulation.
- **Egg Cytoplasm**: Similar to the yolk, this is involved in the development of the embryo and would not contain waste products like uric acid.

5. **Conclusion**: Based on the analysis, uric acid is found in the **egg shell** of sauropsids. This is the correct answer.

### Final Answer:
**Uric acid of sauropsids solidifies and is found in the egg shell.**
