Option (C) 'majority rule' is the odd one out. While free and fair elections, dignity of the individual, and equal treatment before law are fundamental principles that democracies must ensure and protect for all citizens, majority rule is merely a decision-making mechanism. The other three options represent protective principles that safeguard citizens' rights and freedoms. In fact, unchecked majority rule can sometimes threaten individual dignity and equal treatment (tyranny of majority). Democracies must balance majority rule with minority rights and constitutional safeguards. The context emphasises that democracies need to ensure conditions like fair chance to everyone, transparency, and accountability - which align with options A, B and D, not with pure majority rule.
