Mirage is an effect caused by hot air in a desert which makes you think you can see the object when they are not actually there.

It is an optical illusion. So, A is the correct option.

It is Due to total internal reflection of light.

Mirage is on hot summer days the layer of air in contact with the sand becomes hot and rare. When the light rays travel from denser to rarer, they undergo total internal reflection. Thus image of the distant object is seen inverted.

Unequal heating of different layers of atmosphere causes different temperature for different layers and as a result different densities which further adds that the speed of light will be different in these layers (layers will be having different refractive index) ie, white going higher from the surface the refractive index decreases and the layers becomes rearer and light ray going up from surface after passing each layer of atmosphere bends away from normal (because it passes from denser to rearer medium) and at a particular angle it suffers total internal reflection and comes back to the surface and falls on a person eye (this is called a mirage).
