In a federal government system, the states have powers that are granted to them by the constitution. These powers are outlined and specified in the constitution, which serves as the supreme law of the land. The constitution clearly defines the powers and responsibilities of the federal government and the states, ensuring a division of powers between the two levels of government.

Option 1: Original powers refer to the inherent powers that the states possessed before the formation of the federal government. However, in a federal government, the states do not solely rely on their original powers but also receive powers through the constitution.

Option 2: While the Centre may delegate certain powers to the states, it is ultimately the constitution that grants the states their powers, and not solely the Centre`s decision.

Option 4: While the powers are ultimately given by the people through the democratic process, it is the constitution that specifies and guarantees these powers to the states.

Therefore, the correct answer is option 3.
