CorrectNot quiteAnswer D

Correct answer: D

The object is between C and F.
With the object between C and F, the reflected rays meet beyond C, giving a real, inverted, magnified image.

Worth noting

This is the mirror twin of an object between F and 2F for a convex lens. Real images from a mirror form in front of it.
