The election of 1800 revealed what flaw in the u. s constitution that led to the ratification of the twelfth amendment ?

B) The method used by the Electoral College of electing the president and vice-president often resulted in a tie for president.

Explanation:

The Twelfth Amendment indicates what the correct procedures for electing the President and Vice President are. The amendment was proposed in 1803, and was ratified in 1804. One of the main reasons for the amendment was the election of 1800, in which it became clear that if each member of the Electoral College followed party tickets, a tie could be possible. In fact, a tie did occur, between Jefferson and Burr. The experience of this election led to the amendment being passed.
