I still need to understand the meaning of both interference and dispersion.

So please would someone be of help?

Why dispersion isn't the right answer?,

Light produces its component colours due to the dispersion of light. Right?

Correct me if I'm wrong.

Interference of light more specifically, thin film interference.

Reason:

When light falls on the thin oil film, some light reflects from the top surface,

Some reflects from the bottom surface. These reflected light waves interfere with each other. Different wavelengths interfere differently, producing colourful patterns.
