Answer: D. Parliament may amend the Constitution by ADDITION, VARIATION and REPEAL (all three).

The three modes are: (1) Addition: inserting new provisions (e.g. adding Article 21A on Right to Education by the 86th Amendment). (2) Variation: modifying existing provisions (e.g. changing language of Article 31 over various amendments). (3) Repeal: deleting provisions entirely (e.g. removing Article 31 on Right to Property by the 44th Amendment 1978). Subject to the basic structure doctrine (Kesavananda Bharati 1973). All three modes are textually authorised. Source: Article 368 of the Constitution / NCERT Class 11 Indian Constitution at Work Ch 9.
