The correct answer is:
A. They study how light bends around a galaxy or galaxy cluster.
This phenomenon, known as gravitational lensing, occurs because dark matter's mass distorts spacetime, causing light from distant objects to bend as it passes near massive galaxies or clusters. This provides evidence for the presence of dark matter.
