1824, because it was the first with PV, and Jackson, the first president that could be called a "man of the people", had his rightful victory stolen by another rich guy.
By the way, could you give a reason behind the other poll options?
American presidential elections had popular vote going back to 1789, and in both 1789 and 1824, there were some states whose electors were determined popularly, and some where they were determined by the state senate or some other method. Merely because the Atlas doesn't show popular vote shades for pre-1824 elections doesn't mean they don't exist.
