The object is at the center of the curvature of the mirror.
Option (d) is correct.
Explanation:
- A concave mirror is the part of a sphere and is curved inward and has a reflective surface.
- The light falling on the surface of the concave mirror focuses only on one point.
- The image formed by a concave mirror depends on the distance between the object and mirror.
- These mirrors are sued in optical devices such as cameras, telescopes, and microscopes, etc.
