it is easy to generate
B)
rectification is possible
C)

The stars twinkle at night because
A)
they emit energy
B)
of diffraction
C)
of refraction
D)
of relection
Stars twinkle because their light passes through layers of the Earth's atmosphere with varying density. This causes continuous bending of light rays, i.e., refraction, which makes the star's apparent brightness and position fluctuate. Diffraction is not the cause here, and reflection is irrelevant. Stars do emit energy, but that does not explain twinkling.
