C. Economic Policy, because it is a government actions that are intended to influence the economy of a nation, state or city and one of the best example of economic policy is the tax rates-we all know that tax is a percentage of an employees income paid or in company pays or it is a value of a service or goods. If we let people define or talk about tax rates they will say its not good tax rates is to high i don't deserve to pay for it. If federal and state will increase the tax rates at least they will agree to increase the salary of each employees so they can paid their tax and can provide their daily needs.
