If the US Allowed the Export of Significant Amounts of Natural Gas

If the U.S. allowed the export of significant amounts of natural gas, what would be the economic effect?

A) There would be no net economic effect on international trade because increased exports from the U.S.would be offset by increased imports to the U.S.of other goods.
B) The economic effect on international trade would be negative because increased amounts of natural gas in the importing countries would drive down the price of domestically produced natural gas in the importing countries.
C) The foreign demand for natural gas from the U.S.would increase the price of natural gas in the U.S., production of natural gas in the U.S.would increase, and consumption of natural gas in the U.S.would decrease slightly.
D) Increased demand for natural gas form the U.S.in foreign countries would increase the price of natural gas world-wide and result in many countries not being able to afford the price of natural gas.
