Bstays fixed at the centre of curvature
Cmoves from F towards infinity, growing larger
Dmoves from F towards the pole, shrinking
Answer & Solution
Correct answer: C. moves from F towards infinity, growing larger
Object at infinity → image at F (tiny).
As the object approaches F, the real image recedes from F towards infinity and grows.
At F the image is at infinity; inside F it becomes virtual.
