The correct answer is B. incentives.
Tax incentives are a type of government policy that encourages taxpayers to take certain actions by providing them with a financial benefit. For example, the government might offer a tax credit for businesses that invest in research and development, or a tax deduction for individuals who donate to charity.
Tax incentives can be used to achieve a variety of policy goals, such as stimulating economic growth, encouraging innovation, or promoting social welfare. In the context of the question, the government might offer tax incentives to businesses that produce quality goods. This would encourage businesses to invest in quality control and to produce goods that meet high standards. This would, in turn, create a market for quality goods and benefit consumers.
The other options are not as relevant to the question. Tax controls are rules that the government uses to regulate how businesses and individuals pay taxes. Tax revenues are the money that the government collects from taxes. Tax structures are the system of laws and regulations that govern how taxes are levied and collected.
