Predict what will happen to the image produced by a concave lens as the lens gets flatter and flatter- more like a flat piece of glass

The flatter concave lens becomes the  emergent ray moves towards being parallel two incident rays.

Explanation-

A concave lens is a lens that diverges the rays, passing through the lens, from its path thereby appearing to come from a point where image is formed these types of lenses are used by people who find trouble in seeing things that are at a distance. The flatter the lens become it moves more towards becoming a glass slab which refracts the light  such that the emergent ray is parallel two incident Ray but only from another point.  

c. magnitude and direction

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
