Solution

The correct option is C d) Statement A and R both are correct and R is explaining A
Formation of mirages in hot deserts is a phenomena of total internal reflection because in hot deserts air close to the land is heated, so, it is hotter than the air far from the land so, it gives a interface of rarer and denser medium to have total internal reflection.
