Hello @Lucysrv18,
How are you doing? Immediately I can say that answer choice D. is not the answer as a window pane noes not have a curved surface. Also I can say that answer choice B. is out as safety goggles do not have a curved surface.
So your answer is either A. or B. and when you look good you see something in A. I have experience underwater, and I am constantly using Diving Masks. If there is one thing i can assure you about it, its that it does not refract light. The point of the mask is just so water does not enter your pupil. Therefore, B is your answer. An Owl's eye reflects light and contains a "lens" just like a human. Smart Phones have lenses to take photos, and magnifying glasses have lenses to see things closer.
B. is your answer! :)
Thank you,
Darian D.
