Correct answer: A. Justice and accountability
Explanation: Direct answer: Option A, justice and accountability. Rule of law means that everyone, including ministers, officials, and ordinary citizens, must obey clear and fair laws. The law should be applied equally, and public authorities must explain and answer for their actions. Therefore it strengthens justice, because decisions are based on rules rather than personal wishes, and accountability, because officials can be questioned or punished for misuse of power. Option A is correct because it names both results. Option B, arbitrary power, is the opposite: arbitrary power means acting without fair rules. Option C, privilege, means an unfair special advantage; rule of law tries to reduce such unfair treatment, not strengthen it. Option D, secret rule, is also wrong because democratic law should be known and open, not hidden. Memory cue: law means equal treatment plus answerability.
