Answer:
The correct answer is option a.
Explanation:
When a factory closes, its workers become unemployed. Their income declines or disappears. A decrease in income further causes decrease in demand and consumption.
The factory workers will no longer be able to afford restaurant meals, or their demand for meals will decline.
A decline in the demand for meals will adversely affect the revenue and profits of local restaurants.
So, closing up of a factory is a bad news for local restaurants.
