The correct answer is option 1, Fundamental Rights. The Supreme Court of India acts as the guardian for the fundamental rights of the citizens. Fundamental rights are the basic rights that are granted to every citizen of India to ensure their freedom and equality. These rights are enshrined in Part III of the Indian Constitution and include rights such as the right to freedom of speech and expression, right to equality, right to protection from discrimination, and right to life and personal liberty. The Supreme Court has the power to protect and enforce these fundamental rights through its power of judicial review. It can strike down any law or action by the government that violates these fundamental rights.
