For a concave mirror, as an object moves from infinity towards the focus, the real image
Aremains virtual throughout
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.
