Under which article does the Governor of a state withhold his assent to a Bill and reserve the Bill for the consideration of the President?

Article 200 of the Constitution explicitly grants the Governor the power to withhold assent to a Bill passed by the state legislature and reserve it for the President's consideration. The President may then either give assent or direct the Governor to return the Bill to the legislature. Article 201 deals with bills reserved for President's consideration, while Articles 220 and 240 cover different constitutional provisions.
