Select the correct answer using the code given below.

The correct option is 1, 2 and 3.

Article 368 of the Constitution of India outlines the powers and procedures of the Parliament to amend the Constitution. Specifically, Article 368(1) states that the Parliament, in the exercise of its constituent power, may amend any provision of the Constitution in accordance with the prescribed procedure.

The text of Article 368 explicitly defines that an amendment can be carried out through the following three methods:
1. Addition: This refers to adding new articles, clauses, or schedules to the Constitution.
2. Variation: This refers to changing, modifying, or altering the text or scope of existing provisions.
