Correct Option (D)
The passage highlights the indispensable role of opposition in a democracy. It asserts that opponents guide a statesman towards reason and good sense, preventing potential disasters that might arise from unchecked support. The author further states that national unity in a free society relies on a sufficiently even balance of political power. This balance ensures that the administration does not become arbitrary and the opposition does not become revolutionary or irreconcilable. Thus, the opposition is crucial for maintaining political equilibrium and fostering effective governance.
Incorrect Options:
Option (A): This statement contradicts the passage's central argument. The author explicitly states that opponents keep a statesman on the path of reason and show where dangers lie, implying that without opposition, an administration is more likely to become irresponsible and arbitrary, not more responsible.
Option (B): The passage warns against opposition becoming "revolutionary and irreconcilable," indicating that such extremism undermines national unity. It advocates for a balanced political power structure, not for revolutionary elements within the opposition, to keep the government alert.
Option (C): The passage focuses on the opposition's function in ensuring accountability, promoting rational decision-making, and maintaining a balanced political landscape for good governance. It does not suggest that rulers require the support of the opposition for their political survival; rather, it emphasizes the opposition's role in keeping the administration in check.
