Final answer:
Minority leaders in Congress have the power to use filibustering to influence legislation. They can delay a vote on a bill, requiring a supermajority of 60 senators to vote for cloture to end the filibuster and proceed with the legislation.
Step-by-step explanation:
The minority leaders in Congress do not hold veto power, appointment power, or direct committee leadership in the same way the majority does, but they can exert influence through other means. The correct answer from the multiple choices provided is B) Filibustering power. In the Senate, the minority can use the filibuster to extend debate on legislation, effectively blocking or delaying a vote on a bill unless a supermajority of 60 senators vote for cloture to end the debate. This legislative power is significant in that it gives the minority party a strong tool to negotiate, influence, or halt legislation that they do not agree with. It is important to note that the modern filibuster allows for cloture to be requested even before a bill is debated, increasing the vote threshold from a simple majority to a supermajority, which enhances the obstruction power of the Senate minority.
