Gravitational lensing occurs when
A. massive objects bend light beams that are passing nearby.
B. massive objects cause more distant objects to appear much larger than they should and we can observe the distant objects with better resolution.
C. dark matter builds up in a particular region of space, leading to a very dense region and an extremely high mass-to-light ratio.
D. telescope lenses are distorted by gravity.
