Answer:
d) it may be possible for nominal GDP to increase
Step-by-step explanation:
This is the formula to count nominal GDP:
Consumption + Investment + Government Spending + Net Export.
On hindsight, a decrease in production of goods and services tend to lead to a decrease in consumption. Which mean that it will negatively affect the total of nominal GDP.
But, that's not always the case.
There are some cases decrease in consumption might not be as big as the increase in Investment and government spending. So it's still may be possible for nominal GDP to increase.
