Answer: D. removal of the tariff would actually cause domestic output to increase and price to fall.
Explanation:
The tariff led to a situation where the industry being protected became inefficient because it did not have enough competition. This is why they are producing less quantities and at higher prices.
If the tariff was to be removed, the industry would get fresh competition from outside the country. This would force them to become more efficient and the would start producing more goods. Prices would also drop on account of the increased supply from both domestic and foreign companies.
