The correct answer is A. Henry Clay
Explanation:
The 1860 Presidential election in the U.S. took place on November 6 of 1860 and included four main candidates including Abraham Lincoln from the Republican Party that won the elections with his running mate Hannibal Hamlin; the candidate John Brekinrindge from the Southern Democratic Party; the candidate Stephen Douglass from the Northen Democratic party and the candidate John Bell form the Constitutional Union. This implies the one that was not a candidate during this election was Henry Clay who was also a politician but although he was part of the House of Representatives and the Senate he was not a candidate for President and indeed he died in 1852 before the elections occurred.
