Answer:
Refraction by atmosphere
Step-by-step explanation:
The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. ... To our eyes, this makes the star seem to twinkle.

Step-by-step explanation:
Stars twinkle because … they're so far away from Earth that, even through large telescopes, they appear only as pinpoints. ... As a star's light pierces our atmosphere, each single stream of starlight is refracted – caused to change direction, slightly – by the various temperature and density layers in Earth's atmosphere.
option b is correct
