II. Virtual, erect and diminished
Ill. Erect, real and diminished
IV. Erect and magnified

Options

A. I only
B. II only
C. I and III only
D. Ill and IV only.

Explanation

To solve the question about the image formed by the rear-view mirror of an automobile, we need to analyze the properties of the mirror used and the characteristics of the image it produces.

### Step-by-Step Solution:

1. **Identify the Type of Mirror**:
- Rear-view mirrors in automobiles are typically convex mirrors.

2. **Understand Image Formation in Convex Mirrors**:
- Convex mirrors always produce images that are virtual. This means the image cannot be projected on a screen because the light rays do not actually converge.

3. **Characteristics of the Image**:
- The image formed by a convex mirror is always erect. This means that the image is oriented in the same direction as the object.
- The image is also diminished, meaning it is smaller than the actual object.

4. **Conclusion**:
- Based on the properties of convex mirrors, the correct characteristics of the image formed by the rear-view mirror of an automobile are that it is virtual, erect, and diminished.

5. **Final Answer**:
- Therefore, the correct option is **II. Virtual, erect, and diminished**.
