Answer: (C)

Verified step by step guidance

1. Understand the paradox of voting (Condorcet's paradox): it occurs when collective preferences become cyclic (i.e., non-transitive), even if individual preferences are transitive. This means that no option is the clear winner because preferences can loop in a cycle (A preferred to B, B preferred to C, but C preferred to A).
2. Identify the voting systems listed: Borda count method, Unanimous consent, Majority rule voting, and Plurality voting. Each system aggregates individual preferences differently.
3. Recall that the paradox of voting is most commonly associated with pairwise majority voting, where each option is compared head-to-head against every other option, and the majority preference determines the winner in each pair.
4. Recognize that majority rule voting involves these pairwise comparisons, which can lead to cycles in collective preferences, thus illustrating Condorcet's paradox.
5. Conclude that among the options, majority rule voting is the system most commonly linked to the paradox of voting because it directly exposes the possibility of cyclical majorities.
