Assertion (A): PILs are creating new rights and laws within the realm of the state in India.
Reasoning (R): PIL are incorporating the Directive Principles whose claims cannot be brought directly to the Courts, into the domain of fundamental rights under Part III of the Constitution, which can be invoked before the Courts as a matter of rights by the citizens of India.

Both A and R are correct and R is the correct explanation of A.

PIL from its inception is modelled on remedial nature which aims at creating a dynamic, welfare oriented model of judiciary. PIL thus incorporates the Directive Principles whose claims cannot be brought directly to the Courts, into the domain of fundamental rights under Part III of the Constitution, which can be invoked before the Courts as a matter of rights by the citizens of India. Therefore PILs are creating new rights and laws within the realm of the state. These laws are also democratising citizen's access to justice, thereby strengthening the democracy in India.
