Identify the true statement among the following.

Options

A. Both compounds and mixtures are homogeneous.
B. Both compounds and mixtures are heterogeneous.
C. Compounds are homogeneous and mixtures are heterogeneous.
D. Compounds are homogeneous and mixtures can be homogeneous or heterogeneous.

Explanation

To solve the question "Identify the true statement among the following," we will analyze the definitions and characteristics of compounds and mixtures based on the provided information.

### Step-by-Step Solution:

1. **Understand the Definition of a Compound**:
- A compound is a substance formed by combining two or more chemical elements.
- Compounds have a uniform composition, meaning they are homogeneous.

2. **Understand the Definition of a Mixture**:
- A mixture is formed by combining two or more different substances (matters).
- Mixtures can be separated by physical methods.
- Mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition).

3. **Analyze the Options**:
- **Option 1**: Both compounds and mixtures are homogeneous.
- This is incorrect because while compounds are homogeneous, mixtures can be heterogeneous as well.
- **Option 2**: Both compounds and mixtures are heterogeneous.
- This is incorrect because compounds are homogeneous.
- **Option 3**: Compounds are homogeneous and mixtures can be homogeneous and heterogeneous.
- This is correct. Compounds are always homogeneous, while mixtures can be either.
- **Option 4**: (Assuming there is a fourth option) is incorrect based on the definitions provided.

4. **Conclusion**:
- The true statement is: "Compounds are homogeneous and mixtures can be homogeneous and heterogeneous."

### Final Answer:
The correct statement is: "Compounds are homogeneous and mixtures can be homogeneous and heterogeneous."
