Why was the banking industry under investigation by the Nye Committee in 1934?

Questions emerged as to whether banks, as well as munitions factories, played a role in the United States joining World War I.

Senators wanted to uncover the role the banks played in the loss of individual savings accounts during the Depression.

The banking industry was accused of loaning money to Japan after it invaded Manchuria.

The public wanted a full investigation into the loans the banks made to speculative investors in the stock market.

I believe it is A. 
"Nye created headlines by drawing connections between the wartime profits of the banking and munitions industries to America's involvement in World War I. Many Americans felt betrayed and questioned that the war had been an epic battle between the forces of good (democracy) and evil (autocracy). This investigation of these "merchants of death" helped to bolster sentiments for isolationism."
