Treating citizens not merely as subjects but as participants is central to which argument in democracy?

Correct answer: Argument of citizen dignity and participation

The direct answer is A: the argument of citizen dignity and participation. A subject is mainly expected to obey a ruler, while a participant has a voice in choosing representatives, discussing public matters, questioning decisions, and helping shape government. The reasoning is: democracy recognises citizens as equal persons; equal persons deserve to be heard; having a voice and a role gives political dignity. Option A is correct because it directly connects dignity with active participation. Option B, criticism of money power, concerns the harmful influence of wealth and does not explain the subject-participant distinction. Option C, criticism of slow decisions, is an argument against possible delay in democracy. Option D, lack of leaders' expertise, concerns administrative ability, not citizens' status. Exam cue: subject obeys; participant takes part.
