Correct Answer

B

Explanation

The correct statement(s) regarding the use of a convex mirror as a driving mirror are:

I. Its image is erect.
II. It has a large field of view.

Convex mirrors are commonly used as driving mirrors because they provide a wider field of view compared to flat or concave mirrors. Additionally, the image formed by a convex mirror is always virtual, diminished, and erect, making it easier for the driver to see objects behind them. However, convex mirrors have a smaller focal length compared to concave mirrors.
