The correct answer is 3. During the Hoover administration, the Smoot Hawley tariff greatly raised rates on imported products.
The Hawley-Smoot Act was a law passed in the United States on June 17, 1930, proposed by Senators Reed Smoot and Willis C. Hawley, which unilaterally raised US tariffs on imported products, to try to mitigate the effects of the Great Depression that began in 1929. The remarkable feature of this regulation was the notable increase in the tariffs set and its extension to nearly 20,000 imported products, which caused a strong impact on international trade at the time.
