Statement I : Convex mirror is used as a driver mirror.
Statement II : Images formed by convex mirror are
diminished in size.

Options

A. a Both the statements individually true and Statement II is
the correct explanation of Statement I.
B. b Both the statements are individually true but Statement II is
not correct explanation of Statement I.
C. c Statement I is true but Statement II is false.
D. d Statement I is false but Statement II is true.

Explanation

To analyze the statements regarding convex mirrors, we will evaluate each statement independently and then determine their relationship.

### Step 1: Evaluate Statement I
**Statement I**: "Convex mirror is used as a driver mirror."

- **Explanation**: Convex mirrors are commonly used as driver mirrors (side mirrors in vehicles) because they provide a wider field of view compared to flat or concave mirrors. This allows drivers to see more of the area behind them, reducing blind spots and enhancing safety while driving.

### Step 2: Evaluate Statement II
**Statement II**: "Images formed by convex mirror are diminished in size."

- **Explanation**: The images formed by a convex mirror are indeed diminished in size. Convex mirrors produce virtual images that are upright (erect) and smaller than the actual object. This is due to the nature of how light rays diverge after reflecting off the surface of a convex mirror.

### Step 3: Determine the Relationship Between the Statements
- Both statements are true:
- Statement I is true because convex mirrors are used for safety in driving due to their wide field of view.
- Statement II is true because the images formed by convex mirrors are virtual, erect, and diminished in size.

However, Statement II does not explain why Statement I is true. While both statements are correct, Statement II does not serve as a justification for Statement I.

### Conclusion
- Both statements are true, but Statement II is not the correct explanation for Statement I. Therefore, the correct answer is that both statements are true, but Statement II does not explain Statement I.

### Final Answer
Both statements are true, but Statement II is not the correct explanation for Statement I.
