The law of increasing opportunity costs states that:

a. the sum of the costs of producing a particular good cannot rise above the current market price of that good.

b. if the sum of the costs of producing a particular good rises by a specified percent, the price of that good must rise by a greater relative amount.

c. if the prices of all the resources used to produce goods increase, the cost of producing any particular good will increase at the same rate.

d. if society wants to produce more of a particular good, it must sacrifice larger and larger amounts of another good to do so.
