Which of the following pairs of an Article of the Constitution of India and its subject is NOT…

The wrongly matched pair is Article 60 with impeachment of the President. Article 60 prescribes the oath or affirmation taken by the President; the procedure for impeachment is laid down in Article 61. The other pairs are correct: Article 54 provides for the election of the President by an electoral college, Article 55 sets out the manner of that election, and Article 123 empowers the President to promulgate ordinances at any time except when both Houses of Parliament are in session.
