Oil spreads in water interference takes place.

Can give other example for interference?

Why should not dispersion be the correct answer?

@Shru.
Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves or matter waves.

How can two superimposing waves generate different colours?

Interference:
It is due to the super position of the secondary wavelets from two different wave fronts produced by two coherent sources.

What is polarization?

I doubt this ''interference'' as the answer. It should be Dispersion. The oil film acts as a medium which separates white lght into different components, due to the different speed rates of white light components.

I am confused. I think this is due to Dispersion, not interference. Interference pattern consists of white and dark fringes, not on different color like a rainbow.
Would someone can clear my confusion?

The correct answer is dispersion. The oil forms a thin layer on the surface of the wet ground. This layer dispersed the light entering the thin oil layer. This dispersed light is totally internally reflected in the oil.
