Solution

The correct option is D

statement 1 is correct, but statement 2 is incorrect


Since hot air is less dense than the cold air. So light rays when entering, from hot air to cold air, undergoes refraction and bends .Thus object when seen through hot air appears to flicker.

so , statement 2 is wrong. But statement 1 is correct.
