Answer:
The correct answer is option B.
Explanation:
If an economy is working well below capacity this means there is huge amount of unused resources left. Resources or inputs at this point will be available at a relatively lower price. So the firms will be able to expand output at a cheaper rate.
When the demand for inputs increase the input price will not increase much. So, the firms will be able to increase output and the price level will not increase by a great extent.
