If the statement above concerning oil-supply disruptions is true, which of the following policies in an open-market nation is most likely to reduce the long-term economic impact on that nation of sharp and unexpected increases in international oil prices?
(A) Maintaining the quantity of oil imported at constant yearly levels
(B) Increasing the number of oil tankers in its fleet
