- A. The image will accelerate towards the centre of curvature. ✓
- B. The image will accelerate towards the focus.
- C. The image will accelerate towards the pole of the mirror.
- D. The image will move with a constant speed towards the focus.
Correct Answer: A. The image will accelerate towards the centre of curvature.
