Which of these was not a key difference between Northern and Southern states at the Constitutional Convention?

The North and South differed in their economies, settlement patterns, and reliance on enslaved labor: the North had more large cities and industry, while the South depended more on agriculture and slavery. Choosing between direct election and an electoral college was a debate about how to select the president, not a defining difference between the regions. Therefore, the correct choice is A, wanting to elect the president directly versus using an electoral college.
