The correct answer is Option (1) → Civil liberties organisations

Option (1) Civil liberties organisations — Correct. Civil liberties organisations are civil society groups that guard the rights and freedoms of citizens. They have been especially important in keeping a watch on the state and forcing it to obey the law.

Option (2) Trade unions — Incorrect. Trade unions are part of civil society, but they organise workers to pursue their collective interests, such as wages and working conditions. Watching the state and making it obey the law is not the role marked out for them.

Option (3) Women's organisations — Incorrect. Women's organisations take up issues such as campaigns against rape and violence against women. Their focus is justice for women, so the watch on the state is not the role given to them.

Option (4) Both trade unions and women's organisations — Incorrect. Trade unions work for workers' interests and women's organisations work for justice for women. Keeping a watch on the state and forcing it to obey the law is the special role of civil liberties organisations.
