The correct answer is: c) Increasing public investment.
An expansionary fiscal policy is a government policy that is designed to increase aggregate demand in an economy. This can be done by increasing government spending, reducing taxes, or both. Increasing public investment is a type of expansionary fiscal policy because it increases the amount of money that the government is spending. This can lead to increased economic activity, as businesses and consumers have more money to spend.
Reducing taxes is another type of expansionary fiscal policy. When taxes are reduced, people have more money to spend. This can also lead to increased economic activity. However, it is important to note that reducing taxes can also lead to a decrease in government revenue. This can make it difficult for the government to pay for its programs and services.
Controlling inflation is not an example of an expansionary fiscal policy. Inflation is a general increase in prices. When inflation is high, it can make it difficult for businesses to plan and invest. It can also make it difficult for people to afford goods and services. The government can use a variety of policies to control inflation, such as raising interest rates or reducing government spending. However, these policies are not considered to be expansionary fiscal policies.
In conclusion, the correct answer is: c) Increasing public investment.
