D) The extra energy benefits Patrick gets from another can are no longer worth the cost. MB/MC (S)
Explanation:
The optimal quantity for Patrick to consume is 5 cans of GreenCow.
This is the quantity where MARGINAL BENEFIT EQUALS MARGINAL COST. For all quantities up to the 5th, the marginal benefit is higher than the marginal cost. This means that Patrick's net benefit is increasing, and consuming all units up to this point make him better off.
If Patrick were to consume any more than 5 cans of GreenCow, the cost of each additional can would be higher than the additional benefit (because the marginal cost curve is higher than the marginal benefit curve). Consuming any cans beyond the 5th, therefore, makes him worse off.
