  • B. Only B
  • C. Both B and C
  • D. Both A and B
Correct Answer: Option A - When mirror forms an erect and diminished image, this indicates that the image formed so, is also a virtual image and therefore the mirror is of convex nature. A convex mirror also has a positive focal length. Therefore both B and C statements are correct.
