Answer:
The answer is b.
Explanation:
The vice presidential role is mainly to balance the presidential ticket for this reason: the framers of the constitution proposed the vice presidential office in order to give the electoral college a chance to vote from someone that does not belong to their states. The vice president represents the national interest over and above state interests.
The vice president is also in charge of presiding over sessions in the senate, but is only allowed to cast a tie breaking vote. He works together with the presidential nominee by being in charge of senate proceedings, and acts as an intermediary to the presidential nominee by presenting public policy.
