The correct answer is (d), Equality before Law.
A Directive Principle of State Policy is a principle enshrined in the Constitution of India that the State shall strive to achieve. They are not enforceable by any court, but the State is expected to follow them in making laws and policies.
Equality before Law is one of the Directive Principles of State Policy. It means that all persons are equal before the law and are entitled to equal protection of the law. This means that no person can be discriminated against on the basis of caste, creed, religion, sex, place of birth, or any other grounds.
The other options are not Directive Principles of State Policy.
(a) Uniform Civil Code is a code of law that would apply to all citizens of India, regardless of their religion. It is not a Directive Principle of State Policy, but it is a goal that the government has been working towards for many years.
(b) Freedom of the Press is the right of the press to publish news and information without censorship or interference from the government. It is a fundamental right guaranteed by the Constitution of India.
(c) Freedom of Religion is the right of every person to practice their religion without interference from the government. It is a fundamental right guaranteed by the Constitution of India.
