Options

A. the light emitted by the objects reaches our eyes
B. the light emitted by our eyes falls on the objects
C. the light scattered by the objects reaches our eyes
D. the rays of sun fall on the objects

Answer

To answer the question "We are able to see things because...", we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Light Emission and Reflection**:
- Light is emitted from a source (like the sun or a light bulb). This light travels in straight lines and can illuminate objects around it.

2. **Interaction with Objects**:
- When light hits an object, it can either be absorbed, transmitted, or reflected. Most objects reflect some light, which is what allows us to see them.

3. **Light Reaching Our Eyes**:
- The reflected light from the object travels through the air and reaches our eyes. This is crucial because our eyes need light to perceive an object.

4. **Formation of Images**:
- Once the light enters our eyes, it hits the retina at the back of the eye, where it is converted into signals that are sent to the brain.

5. **Perception of Objects**:
- The brain processes these signals, allowing us to see and recognize the objects around us. Therefore, we see objects because the light scattered or reflected from them reaches our eyes.

### Conclusion:
We are able to see things because light scattered by the object reaches our eyes, allowing us to perceive the object.
