Correct answer: D. Freedom of assembly and expression was affected
Explanation: The direct answer is D: freedom of assembly and expression was affected. A peaceful protest is a lawful way for citizens to express disagreement and gather with others. Reason step by step: the protest is peaceful, so no violence or immediate danger is stated; the government uses force without a valid reason; unnecessary force prevents people from speaking and meeting; therefore two connected civil liberties are harmed. Option A, strengthened rule of law, is wrong because rule of law means authorities also follow fair, known rules and do not use arbitrary force. Option B, increased respect for rights, is the opposite of what happened: unjustified force shows disrespect. Option C, protected civil liberty, is also opposite because the liberty was restricted, not protected. Option D is correct because both assembly and expression are affected by stopping a peaceful protest. Exam cue: the word “peacefully” matters; peaceful criticism normally deserves protection, while force requires a lawful and reasonable justification.
