Answer:
Option B. The country's GDP will increase by $12,000
Step-by-step explanation:
This can be explained by using the following formula:
GDP = Consumption + Investment + Government Spending + (Exports - Imports)
This means that if the consumption of consumers is increased then the Gross Domestic Product will increase. In this case, the increase in the consumer spending by $12,000 would increase the GDP by the same amount. So the option B is correct here.
