Tariffs were another issue upon which the North and South disagreed that intensified sectional feeling.

Option C

Explanation:

The sectionalism was based on the fact of slavery, where northerners wanted to abolish slavery but southerners did not as they were dependent upon cash crop which was labour intensive. The other issue which raised to heights were the tariff.

North America supported the tariff based on the fact that the tariff would let them establish competition with the Britain. But the southerners were not in support as they were at drawback due to the import of goods priced much more.  Hence, North America and South America divided themselves based on the sectional diversion which was intensified.
