For a constitutional amendment with respect to which of the above, ratification by the Legislatures of not less than one-half of the States is required before presenting the bill to the President of India for assent?

• Any amendment to these lists directly impacts the federal division of powers.
• Article 368(2) explicitly states that amendments seeking to make any change in “any of the Lists in the Seventh Schedule” require ratification by at least half of the State Legislatures.
• Therefore, this statement is correct.

II. Extent of the executive power of a State:

• The executive power of the Union and the States is a fundamental aspect of India’s federal system.
