Oil spillage in ponds and creeks can be cleaned by ____________
A. burning off the oil layer B. spraying with detergent C. spraying with common salt D. spraying with hot oil
Correct Answer: B
Explanation
If there is oil spillage on a body of water, the best way to clear it is to add some dispersants, which can come in form of some detergents. These aids in dispersing the oil over a very large surface. If it is on a soil, the best way is to introduce some oil-consuming bacteria.
