Question

1. what happens if no presidential candidate wins a majority of electoral votes?

the parties schedule a second election.
the candidate that wins the largest state wins the election.
the election is decided by a vote in the house of representatives.
the senate asks one candidate to withdraw.

Explanation:

To solve this, we refer to the U.S. electoral process. If no presidential candidate gets a majority of electoral votes, as per the 12th Amendment, the House of Representatives decides the election (each state delegation has one vote, choosing from the top three candidates). The other options are incorrect: there's no second election for this scenario, winning the largest state isn't the rule, and the Senate doesn't ask a candidate to withdraw for this.

Answer:

The election is decided by a vote in the House of Representatives.
