The correct answer is A) a high unemployment rate.
The issue that arose under Hoover and helped Roosevelt into the White House in 1932 was a high unemployment rate.
After the Great Depression due to the crash of the market stock, many people lost their jobs, many companies closed and Banks declared bankruptcy. The country faced many economic problems and a high unemployment rate was one of the most difficult to resolve. This situation favored Franklin D.Roosevelt to get to the Presidency in 1932. People were tired of this situation and were anxious for a change. Roosevelt gave them this possibility and the U.S. citizens voted for Roosevelt.
