We are able to see through a.... medium as light is transmitted through it.

Options

A. Opaque
B. Transparent
C. Translucent
D. Rough

Explanation

To answer the question, "We are able to see through a.... medium as light is transmitted through it," we need to identify the type of medium that allows light to pass through, enabling us to see objects.

### Step-by-Step Solution:

1. **Understanding the Concept of Medium**:
- A medium is a substance through which light can travel. Different mediums can affect how light behaves.

2. **Identifying Types of Mediums**:
- There are three main types of mediums based on their ability to transmit light:
- **Transparent Medium**: Allows light to pass through with minimal scattering (e.g., clear glass, water).
- **Translucent Medium**: Allows some light to pass through but scatters it (e.g., frosted glass).
- **Opaque Medium**: Does not allow light to pass through (e.g., wood, metal).

3. **Focusing on the Question**:
- The question specifically asks about a medium that allows us to see through it. This implies that light must be transmitted effectively.

4. **Conclusion**:
- The correct answer is **Transparent Medium**. This is because a transparent medium allows light to pass through without significant obstruction, enabling us to see objects clearly.

### Final Answer:
We are able to see through a **transparent medium** as light is transmitted through it.
