Answer:
B. Reducing unemployment
Step-by-step explanation:
The government, in this case, is using expansionary fiscal policies to create employment. Hiring people to build dams, repair roads, and install power lines leads to an increase in the government's spending in the economy. Consequently, a higher number of people will be working and earning. Increased earnings cause the aggregate demand to rise.
A reduction in business taxes reduces production costs. Businesses will be able to increase production, expand, and hire more workers when the cost of doing business is low.
