Which of the following phenomenon occur when a cluster of stars warps the fabric of space?

Question

Gravitational lensing is a phenomenon that occurs when a cluster of stars warps the fabric of space. This creates a sort of massive magnifying glass that distorts and amplifies the light from distant objects behind it. In effect, these are natural, cosmic telescopes. These large celestial objects will magnify the light from distant galaxies that are at or near the peak of star formation.
Einstein cross is a phenomenon that occurs when the star we are observing is exactly behind the intervening large galaxy and there are four images of the star produced around the galaxy’s image.
If it is slightly away from the line joining us on earth and the galaxy, but behind the galaxy, the image we capture will be like an arc of light.
