“The sun appears to be flattened during sunrise and sunset. This is due to atmospheric refraction.”
Identify whether the above statement is true or false.

The correct answer is 'True'.

The sun appears flat when near the horizon on account of refraction of light. The atmosphere is made up of different layers of air each having a slightly different refractive index. This change in refractive index with layers causes uneven bending of sunlight.
So this is True
