The correct answer is: Social and economic justice.
The Directive Principles of State Policy are a set of principles that are enshrined in the Indian Constitution. They are not enforceable in a court of law, but they are nevertheless fundamental in the governance of the country. The Directive Principles aim to provide social and economic justice to all citizens, and to promote the welfare of the people. They also aim to secure justice, liberty, equality, and fraternity for all citizens.
The Directive Principles are divided into three categories: economic, social, and political. The economic Directive Principles aim to promote economic development and social justice. They include principles such as the right to work, the right to education, and the right to health. The social Directive Principles aim to promote social welfare and equality. They include principles such as the right to equality, the right against discrimination, and the right to freedom. The political Directive Principles aim to promote democracy and good governance. They include principles such as the right to freedom of speech, the right to freedom of assembly, and the right to freedom of association.
The Directive Principles are an important part of the Indian Constitution. They provide a framework for the government to follow in order to promote the welfare of the people. They also serve as a guide for the judiciary in interpreting the Constitution.
The other options are incorrect because they are not the primary aim of the Directive Principles of State Policy. Individual liberty is a fundamental right that is guaranteed by the Constitution. Religious freedom is also a fundamental right that is guaranteed by the Constitution. Separation of powers is a principle of government that is not explicitly mentioned in the Constitution, but it is nevertheless an important principle that is followed in India.
