Who has the final authority for making laws in India?

Parliament

The correct answer is Option 3 - Parliament

In India, the Parliament has the final authority for making laws.

The Parliament of India derives its authority to make laws from the Constitution of India, which is the supreme law of the land. Article 245 of the Constitution empowers the Parliament to make laws for the whole or any part of the territory of India.
The process of law-making in India involves the introduction, discussion, and passage of bills in either house of Parliament (Lok Sabha or Rajya Sabha). Once a bill is passed by both houses and receives the President's assent, it becomes law.
The Parliament has exclusive jurisdiction to make laws on matters enumerated in the Union List (List I) of the Seventh Schedule of the Constitution. These matters include subjects of national importance such as defense, foreign affairs, currency, and communication
