PLEASE ANSWE

Larry is looking through a lens at a grasshopper. He wants to get a better look at the grasshopper's back legs, but instead of looking larger the legs look smaller. What happened?

A. Larry must have grabbed a concave lens since the legs look smaller.
B. Larry must have grabbed a concave lens since the legs are upside down.
C. Larry must have grabbed a convex lens since the legs look smaller.
D. Larry must have grabbed a convex lens since the light rays are diverging (spreading out).

A. Larry must have grabbed a concave lens since the legs look smaller.

Explanation:

I'm not sure. I did some research and it seems that this is the correct one because, universe today.com said; "A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia)." and passmyexams.co.uk said; "Convex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens.   When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.  The distance between the principal focus and the centre of the lens is called the focal length." and so, this lead me to believe that the answer is; A. Larry must have grabbed a concave lens since the legs look smaller.

i'm assuming that the correct answer is indeed the first one/ "a"..
