Correct option is (c) Gravitational Lensing

To explain I would say: Gravitational lensing refers to the distribution of matter between the light source and the observer such that it can bend the light coming from the source to the observer. According to Einstein’s theory of special relativity, it happens because a massive object can alter the space-time frame around itself.
