Which of the following are matters on which a constitutional amendment is possible only with the ratification of the legislatures of not less than one-half of the States? 1. I. Election of the President 2. II. Representation of States in Parliament 3. III. Any of the Lists in the 7th Schedule 4. IV. Abolition of the Legislative Council of a State. Choose the correct answer from the codes given below:

1. The question asks about matters requiring a constitutional amendment that needs ratification by the legislatures of at least half of the States. 2. Article 368 of the Constitution outlines the procedure for amendment. Certain provisions related to the federal structure require this special majority plus state ratification. 3. I. Election of the President: Manner of election (Article 54 and 55) relates to the federal structure and requires state ratification for amendment. 4. II. Representation of States in Parliament: This directly affects the states' role in the federal structure and requires state ratification. 5. III. Any of the Lists in the 7th Schedule: Distribution of legislative powers between Union and States is fundamental to federalism; amendment requires state ratification. 6. IV. Abolition of the Legislative Council of a State: Article 169 allows Parliament to abolish or create a Legislative Council by a simple majority if the state's Legislative Assembly passes a resolution by a special majority. This does *not* require a constitutional amendment under Article 368, let alone state ratification by half the states. 7. Therefore, matters I, II, and III require ratification by the states. 8. The correct combination is I, II, and III.
