The Majority Leader is the highest ranking member of the party in the Senate that has control of the Senate. Their number #2 is the party whip, who is responsible for handling vote counts and ensuring that the party votes as a unified block.
John Cornyn of Texas is the current Senate Majority Whip.
The correct answer is A. The Party Whip is responsible for making sure the party is unified. Both the Majority and Minority parties have a whip, but if the Majority leader is absent the Whip becomes the leader of the party.
