The correct answer is Option C. Collecting taxes is an important part of a country's fiscal policy. Fiscal policy is the use of government spending and taxation to influence the economy. Through taxation, the government can collect revenues to fund its own operations or to redistribute wealth. Taxes can also be used to modify economic behaviour, such as discouraging certain activities or encouraging others. Taxation is an important tool for a government to manage its finances, fund public services, and respond to economic conditions.
