Answer: The correct answer is Option b.
Step-by-step explanation:
There are two types of spherical mirrors:
1. Concave mirror: These mirrors are the mirrors which are converging in nature. These mirrors converge the light rays falling on it on one point. The image formation of these mirrors depends on the position of the object.
2. Convex mirror: These mirrors are the mirrors which are diverging in nature. These mirrors diverge the light rays falling on it. The image formed by this mirror is always upright and smaller than the object.
Hence, the correct answer is Option b.
