The correct option is C
In 1932 the Democratic candidate Franklin D. Roosevelt won the presidential election and began a period of public spending unprecedented in American history to combat the Great Depression. Roosevelt made gestures aimed at granting new rights to African-Americans, and his policies also saved many of them from unemployment and poverty. Since the Roosevelt administration, the black vote was changing regularly to have supported the Republicans to form a solid bloc in favor of the Democrats. Ironically, in those years the Southern Democratic Party was the most powerful opponent to the advancement of civil rights for African Americans.
