What need is fulfilled by federal arrangement or division of powers in a Constitution?

Correct answer: To divide governing responsibilities at different levels

Direct answer: C is correct. A federal arrangement distributes constitutional powers and responsibilities among different levels of government, such as the national, state and local levels. The purpose is to govern a large or diverse country more effectively while allowing each level to handle matters suited to it. C is correct because it describes the sharing of responsibility rather than concentration of power. A is wrong because federalism brings regions into governance instead of excluding them. B is wrong because keeping all power at the centre is centralisation, not federal division. D is wrong because federal arrangements do not exist to end rights. The exact powers depend on the Constitution, so one level is not automatically superior in every matter. Memory cue: federalism means sharing power across levels.
