Answer:
The correct answer is A. The purpose of the Twelfth Amendment is to allow the electors to cast separate ballots for president and vice president.
Step-by-step explanation:
The Twelfth Amendment to the US Constitution was passed by Congress on December 9, 1803. Ratified by the required number of states June 15, 1804. This amendment establishes the election process for the President of the United States and Vice President of the United States. This amendment replaced Article 2, Section 1, Clause 2 of the Constitution, which had previously regulated the electoral process. The amendment was adopted in connection with the problems that arose in the 1800 elections.
