Which of the following is enforceable by the Indian Constitution?

Correct option is B

Fundamental rights are explicitly provided in Part III of the Indian Constitution and are enforceable by the courts.
 Citizens can approach the judiciary if they believe their fundamental rights have been violated.
 These rights include the right to equality, right to freedom, right against exploitation, right to freedom of religion, cultural and educational rights, and right to constitutional remedies.
 The Preamble to the Indian Constitution serves as an introduction to the Constitution, stating its objectives such as Justice, Liberty, Equality, and Fraternity. It is not enforceable in a court of law, meaning one cannot cite only the Preamble in a court case to claim any rights.
 Outlined in Part IV of the Constitution, the Directive Principles are guidelines to the central and state governments to be kept in mind while framing laws and policies. They are non-justiciable, which means they are not enforceable by courts and cannot be used to seek redressal from the judiciary.
 Incorporated by the 42nd Amendment in 1976, the Fundamental duties are listed in Article 51A of the Constitution. These duties, such as respecting the Constitution, the national flag, and the national anthem, promoting harmony, safeguarding public property, etc., are moral obligations for all citizens but are not enforceable by law.
