Detailed Solution

Objects are between F and C. As a point object moves between C and F, images moves between C and $\infty$ . Since A is farther than B,
image of A will be closer. A and B have same height but their images will have different height due to difference in magnifications. Hence, image of AB will be inclined.
For a concave mirror $m a g n i f i c a t i o n = \frac{- v}{f} + 1$ , So the image formed by AB will be straight line.
