The correct answer is (d), Right to Information.
Directive Principles of State Policy are principles that are laid down in the Constitution of India and are fundamental in the governance of the country. They are not enforceable by any court, but the state is supposed to apply them while making laws and policies.
The Right to Information is not a Directive Principle of State Policy. It is a fundamental right that was added to the Constitution in 2005. It gives citizens the right to access information held by the government.
The other options are all Directive Principles of State Policy. Prohibition of Liquor is a principle that states should try to prohibit the consumption of liquor. Equal pay for equal work is a principle that states should ensure that men and women are paid equally for the same work.
I hope this helps!
