Southern states threaten to nullify the tariff on imports enacted by Congress in 1828 because the tariff caused imports to cost more which hurt Southern states.
Answer: Option B
Step-by-step explanation:
The tariff that the Congress enacted in the year 1828 on the imports from the English people in the United States caused the imports to cost more to improve the sale of the domestic products and reduce the imports from the European countries.
Since the manufacturers were mostly in the Northern part, the income from the tariff benefited those northern manufacturers only and it had an adverse affect on the Southern states.
