Correct answer: D. Expression and fearless participation
Explanation: The direct answer is D, expression and fearless participation. A democratic society allows people to express opinions, ask questions, disagree, and take part in public life without threats or unjust punishment. The reasoning is: a person can participate meaningfully only when fear does not silence them; free expression lets different views enter discussion; participation allows citizens to influence decisions and hold authorities responsible. Option A, hereditary right, means an inherited privilege and has no necessary connection with speaking freely. Option B, secret rule, suggests decisions are hidden from people, which is contrary to openness and public participation. Option C, discrimination, means unfair treatment based on identity or status; allowing people to speak without fear points in the opposite direction. Option D is correct because freedom of expression and fearless participation are broad democratic values. This does not mean that every statement is free from all legal limits; it means people should not be silenced merely for holding or peacefully expressing opinions. Exam cue: no fear plus the ability to speak and join public affairs indicates democratic participation.
