Answer:
Crude oils
Explanation:
The correct word should be crude oils.
Crude oil is a non-renewable resource that is geologically formed and found deep in the ground. It is a naturally occurring mixture of hydrocarbons and usually fractionated to serve different purposes for the use of man. Crude oils are non-renewable because the rate at which humans exploit them is quite faster than the rate at which they are being naturally replenished deep in the ground.
