The correct answer is "D"
The US presidential election of 1860 was the nineteenth quadrennial presidential election to elect the president and vice president of the United States. The election was held on Tuesday, November 6, 1860. In a four-way competition, the ticket of the Republican Party of Abraham Lincoln and Hannibal Hamlin came out triumphant. The election of Lincoln served as the main catalyst of the American Civil War.
Despite the minimal support in the south, Lincoln won a plurality of popular vote and a majority of the electoral vote. The divisions among Republican opponents were not in themselves decisive in securing the Republican capture of the White House, since Lincoln received absolute majorities in the states that combined for the majority of the electoral votes. Lincoln's main opponent in the North was Douglas, who finished second in several states and in the popular vote, but only won the slave state of Missouri and three electors of the New Jersey Free State. Bell won three states in the High South: Virginia, Kentucky and Tennessee, while Breckinridge swept the rest of the south. The election of Lincoln led to the secession of several southern states, and the Civil War would begin with the Battle of Fort Sumter.
