The correct answer is A)

Explanation:

From 1815 to 1860, southern production of cotton represented more than half of all American exports.

The American South is known for its temperate weather and rich agri-friendly topography, making it an ideal location for growing cotton. All the southern seaports and riverside docks which are numerous in number permitted shipping of cotton to remote destinations.

By 1860, Southern plantations supplied 75% of the world's cotton, with shipments from Houston, New Orleans, Charleston, Mobile, Savannah, and a few other ports.
