The correct answer is D) all of these.
What was true about the election of 1800 was the following. A tie in the electoral college sent the election to the House of Representatives, Hamilton influenced the House of Representatives to vote for Jefferson, and power peacefully transferred from one political party (centralized) to the other (de-centralized).
In the history of the United States election, there have been some complicated and defying moments, but the election of 1800 can be set apart. Known as the "Revolution of 1800" for its implications, in this election, the candidate of the Democratic-Republican Party, Thomas Jefferson, won the election defeating his Federalist party rival John Adams. During the campaign, the candidates attacked and accused each other of many things. Federalists wanted more power for the strong central government and former anti-federalists, the Democratic-Republican party, wanted more freedom to counter-attack the power of the government.
