Answer: The correct answer is Option D.
Explanation: There are 2 types of spherical mirrors:
1. Convex mirror: These mirrors have shiny surface on the outer side of the curvature. The image formed by these mirrors are always virtual, upright and smaller in size.
2. Concave mirrors: These mirrors have shiny surface o the inner side of the curvature. The image formed by these mirrors can be real and inverted or virtual and upright depending on the placement of object. If the object is placed at the distance greater than the focal length, the image produced will be real and if it is placed at the distance smaller than the focal length, the image produced will be virtual.
Hence, the correct answer is Option D.
