To which of the following Bills the President must accord his sanction without sending it back for…

The correct choice is: Money Bills

Under Article 111 the President may return a Bill, other than a Money Bill, to Parliament with a message asking the Houses to reconsider it. A Money Bill is introduced only on his prior recommendation, so it cannot be returned for fresh consideration.

Ordinary Bills and other Bills passed by both Houses can be returned under Article 111. A State Bill reserved for the President's consideration can also be sent back: under Article 201 he may direct the Governor to return it (unless it is a Money Bill) to the State Legislature for reconsideration.

Hence the answer is ‘Money Bills’.
