Options

A. the left eye as green and right eye as blue
B. the lift eye as blue and right eye as green
C. both the eyes as green
D. both the eyes as blue

Answer

To solve the problem, we need to analyze the situation of the girl standing in front of a plane mirror and how the colored contact lenses affect what she sees in her image.

### Step-by-Step Solution:

1. **Identify the Colors of the Contact Lenses**:
- The girl has a blue contact lens in her left eye and a green contact lens in her right eye.

2. **Understand the Concept of Lateral Inversion**:
- When an object is placed in front of a plane mirror, the image formed is laterally inverted. This means that the left side of the object appears on the right side of the image and vice versa.

3. **Determine the Position of the Lenses in the Image**:
- In the mirror, the left side of the girl (which has the blue lens) will appear on the right side of the image.
- Conversely, the right side of the girl (which has the green lens) will appear on the left side of the image.

4. **Assign Colors to the Image**:
- Since the left side (blue lens) is now on the right side of the image, the right side of the image will show blue.
- Similarly, the right side (green lens) is now on the left side of the image, so the left side of the image will show green.

5. **Conclusion**:
- Therefore, in the image reflected in the mirror, the girl will see a blue color on the right side (originally her left eye) and a green color on the left side (originally her right eye).

### Final Answer:
In the image, the girl observes that the left side appears green and the right side appears blue.
