According to the Constitution of Pakistan, a demand for a grant, which is a request for funds from the Federal Consolidated Fund, can only be made on the recommendation of the Federal Government. This ensures that the executive branch is responsible for proposing expenditures.
Option A is false because provincial governments do not have the authority to recommend demands for grants from the Federal Consolidated Fund; their financial jurisdiction is separate.
Option C is false because while the Prime Minister heads the Federal Government, the constitutional requirement specifies the recommendation of the 'Federal Government' as a collective entity, not solely the Prime Minister.
Option D is false because demands for grants require a formal recommendation to maintain financial discipline and accountability, preventing arbitrary spending.
