Correct answer: B. One value is violated
Explanation: The direct answer is B: the one-value condition is violated. Equal vote numbers are not enough if social rank changes the weight given during counting. Reasoning: each person may have received one ballot, but the counting rule adds extra importance because of status; therefore one person’s political influence becomes greater than another’s; the equal-value requirement fails. Option A is wrong because one person, one vote alone is insufficient when weights differ. Option B is correct because the unequal social-rank weight directly violates one value. Option C is wrong because free voting concerns whether people can choose without force or improper pressure; unequal counting is a different problem. Option D is wrong because a voter list concerns who is registered or eligible, not whether votes have equal weight. This example teaches why the principle has three words: one person, one vote, one value. The last part must be checked separately. Memory cue: equal number plus unequal weight still means political inequality.
