Correct answer: C. Whether the limit is based on law valid reason and fair procedure
Explanation: Direct answer: Option C: whether the limit is based on law, a valid reason, and fair procedure. A democratic restriction on a right must not be arbitrary. The government should have legal authority, a legitimate and reasonable purpose, and a fair process that allows explanation or review. Option A is insufficient because popularity cannot make an unlawful restriction valid. Option B is wrong because a leader's personal preference is not a democratic test. Option C includes the essential checks: law, reason, and procedure. Option D is opposite to democratic accountability; secret restrictions are difficult to examine and challenge. Memory cue: test every rights limit with L-R-P: lawful, reasonable, and procedurally fair.
