Explanation:

Supreme Court of India (Correct): The Supreme Court of India is considered the guardian and final interpreter of the Indian Constitution. It has the power of judicial review, meaning it can strike down any law or executive action that violates the basic structure or any provision of the Constitution, thereby protecting fundamental rights and ensuring constitutional limits. President of India: The President is the head of state, taking an oath to defend the Constitution, but their role is primarily ceremonial and executive, not judicial guardianship. Prime Minister of India: The Prime Minister is the head of government, responsible for implementing laws, but not for interpreting or guarding the Constitution judicially. Election Commission: This autonomous body ensures free and fair elections and does not have the role of guarding or interpreting the Constitution.
