What role does the opposition party serve in a political system?

The opposition party plays a crucial role in a political system by critiquing government policies and holding the ruling party accountable for its actions. This function is vital for maintaining a balance of power and ensuring that the government is responsive to the needs and concerns of the public.

By scrutinizing decisions made by the ruling party, the opposition can highlight potential issues or failures in governance, thereby fostering transparency. It serves as a check on power, encouraging healthy debate and discussion which can lead to better policymaking. This accountability mechanism helps to prevent abuses of power and promotes democratic principles within the political system.

While the other options may have some elements of truth, they do not capture the fundamental purpose of the opposition party. Supporting the ruling party does not align with the opposition's role, and proposing new laws or monitoring global human rights are not central functions of an opposition party in most political systems. Instead, these activities may be part of their broader responsibilities but are secondary compared to their primary role of oversight and critique.
