The correct answer is C) the impact of the French Revolution.
Thomas Jefferson's reaction to the Jay Treaty as expressed in the letter was most directly a reflection of ongoing debates in the US over the impact of the French Revolution.
The Jay Treaty was signed by the government of the United States and Great Britain on November 19, 1794, in London, England. It was signed trying to resolve many difficulties and conflicts between the two nations after the Revolutionary War of Independence.
In a letter written to James Monroe on September 6, 1795, Thomas Jefferson expressed his concerns about the articles included in the treaty and the repercussions to the French government.
The Federalists and their supporters believed that believed in regional
control, with devolution in government, but an equal division of power.
They would have favoured a number of characteristics of modern
government, such as there being different laws in each state and
different representatives for each state proportionally.
