The correct option is
B The placement of the capital of the United States on the Potomac River.
Hamilton knew that he needed Jefferson's support to carry out his
financial program, so he compromised on the location of the permanent
capital, agreeing to locate it in the South on the Potomac River.
Hamilton did not modify his economic program (A), including his support
for excise taxes (E).
He did support the candidacy of his archenemy
Jefferson in the election of 1800, when that election was thrown into
the House of Representatives for resolution (C), but this occurred
almost a decade after he had implemented his financial program.
Hamilton
was pro-British, while Jefferson was more supportive of the French
Revolution. Hamilton would not be conceding anything to Jefferson by
working out a treaty with England (D).
