Answer:
The answer is: B) Equilibrium price and quantity of oil will decrease.
Explanation:
When a company or a family installs extra insulation in their buildings or homes, then they will end up spending less money on both their electricity and heating bills. That will result in a lower demand for oil, so the price of oil will go down. As oil prices go down, the oil companies will decrease the oil supply until a new equilibrium point is reached.
