Among the following which one is homogeneous?

Options

A. Colloid
B. Compound
C. Suspension
D. Mixture

Explanation

To determine which of the given options is homogeneous, we need to understand the definitions and characteristics of homogeneous and heterogeneous substances.

### Step-by-Step Solution:

1. **Understand Homogeneous Mixtures**:
- A homogeneous mixture is one where the components are uniformly distributed and cannot be distinguished from one another. The composition is consistent throughout the mixture.

2. **Identify the Options**:
- We need to look at the provided options (not listed in the question) to analyze each one.

3. **Analyze Each Option**:
- **Colloid**: A colloid consists of one substance dispersed in another. It does not have a fixed composition and shows two phases (the dispersed phase and the continuous phase). Therefore, it is not homogeneous.
- **Compound**: A compound is formed when two or more different types of atoms are chemically bonded together in a fixed ratio. For example, water (H₂O) is a compound made of two hydrogen atoms and one oxygen atom. The composition is fixed and uniform throughout, making it homogeneous.
- **Mixture**: A mixture can be either homogeneous or heterogeneous. If the components are not uniformly distributed and can be distinguished, it is heterogeneous. If they are uniformly mixed, it is homogeneous. However, without specific details about the mixture, we cannot assume it is homogeneous.

4. **Conclusion**:
- Based on the analysis, the only option that is definitively homogeneous is the compound. Therefore, the answer is the compound.

### Final Answer:
- The homogeneous substance among the options is the **compound**.
