Why are roles of different institutions necessary in a major decision?

Correct answer: So division of power and checks are maintained

Correct answer: A. Major decisions affect many people, so concentrating all authority in one person or one institution creates a risk of mistakes, misuse and lack of accountability. Different institutions perform different but connected functions: the political executive proposes and implements policies, Parliament discusses and scrutinises them, and courts can examine their legality and constitutionality. This division of work creates checks and balances, encourages debate and makes decision-makers answerable. B is wrong because one-person rule removes institutional control. C is wrong because democratic institutions are meant to represent and protect public interests, not eliminate the people’s role. D is wrong because institutions operate under and help enforce the Constitution. Memory cue: separate roles do not merely slow decisions; they make power answerable and balanced.
