option B is correct.

Explanation:

From the plot of the graph in the question we can see that there was a rise in the unemployment rate in the year 1929 from around 3.2 percent to 25 Percent in the year 1933. This period in the United States of America then was called the period of great depression. During this period of great Depression the stock market crashed, the gross domestic product (GDP) declined by 30 percent and the the unemployment rate reached 25 Percent. The 25 Percent of unemployed people in 1933 is about fifteen (15) million.

The President during this period of great depression was Herbert Hoover who took the blame for this.

The options A, C and D can never be right, we are talking of rise in unemployment rate. So, option B is the correct option.
