UPSC NDA-1 – 2015
The correct answer is A) the powers of the Parliament of India to amend the Constitution.
Article 368 of the Constitution of India exclusively deals with the power of the Parliament to amend the Constitution and the procedure for doing so. It outlines the special majority required for constitutional amendments.
Option B, financial emergency, is dealt with under Article 360. Option C, To protect the Sovereignty, Unity and Integrity of India, is mentioned as a Fundamental Duty (Article 51A) and also reflected in the Preamble, but not the subject of Article 368. Option D, To render compulsory military service, is not a subject dealt with by Article 368, nor is it a fundamental duty (though providing national service when called upon is a duty).
