The correct answer is statement A.

The Smoot-Hawley Tariff of 1930 resulted in an increased tax on more than 20,000 goods that were imported from other countries. The goal of this tariff was to protect American businesses and to encourage American citizens to made products made in the US. However, this actually ended up hurting the US. The countries whom they traded with responded with their own set of economic punishments (like tariffs) against the United States.
