Although the long-run equilibrium price of oil is 80 per barrel, some producers have much lower costs because their oil reserves are relatively close to the surface and are easier to extract.
 
  If the low-cost producers have a minimum LAC equal to 20 per barrel, then the difference (60 per barrel) is: A) an above-normal economic profit.
  B) an economic rent due to the scarcity of low-cost oil reserves.
  C) a profit that will go to zero as new oil producers enter the market.
  D) none of the above
