Which method is used for an oil spill out at sea to break the oil into small droplets? a, burning b, booming c, dispersion d, skimming

C.Dispersion

Explanation:

Dispersion is the method in which mixtures of emulsifiers and solvents known as dispersants are used to break the oil into smaller particles for the purpose of cleaning the oil spill.

Since the particles are broken down into smaller droplets they get easily dispersed in the water body and then their biodegradation by microbes takes place which allows for the cleanup.
