The correct answer is D. President John Adams and Vice President Thomas Jefferson belonged to different political parties and did not agree on government policy.
The election of 1796 was significant because it marked the first contested presidential election in the United States and highlighted the growing divide between the Federalists, led by John Adams, and the Democratic-Republicans, led by Thomas Jefferson. This election resulted in a president and vice president from opposing parties, which led to increased tensions and conflicts in the government.
