If scientists discover a new form of energy that cuts the cost of producing electricity to the equivalent of $10 a barrel, what will happen to the market for oil?

The supply of oil will decrease because few suppliers can profitably produce oil at $10 a barrel.

There will be no effect on the market for oil.

Demand for oil will decrease over time since no one will pay more than $10 for a barrel of oil to produce energy.

The price of oil will rise because of the competition from the new energy source.
