The correct answer is option 2. Option 2 states that the Directive Principles of State Policy can override all the fundamental rights, which is not correct. The Directive Principles of State Policy are a set of guidelines and principles given to the government to establish social and economic democracy in the country. They are not legally enforceable in a court of law, as mentioned in option 1. This means that individuals cannot directly approach the court to enforce these principles.

Option 3 is correct, as the Directive Principles of State Policy can be related to social and economic justice. These principles aim to promote social justice by striving to eliminate inequalities and ensure equal opportunities for all. They also facilitate economic justice by promoting equitable distribution of resources and ensuring a fair and just economic system.

Option 4 is also correct, as the Directive Principles of State Policy can be related to giving free legal aid. One of the principles is to provide free legal aid to economically weaker sections of society to ensure access to justice for all.

Therefore, the correct answer is option 2, as the Directive Principles of State Policy cannot override all the fundamental rights.
