Answer:
A) is so high that it eliminates imports.
Step-by-step explanation:
Prohibitive tax is one that aims to discourage importers of a good from bringing them into a country.
The tax rate is so high that it will make no sense for the importer to bring in such products.
For example if the tax rate of a product is set to 500% tarrif levy, it will most likely not make sense to bring it into a country at all.
The final price that will be presented to the customer will be too high for the importer to sell.
