I am pretty sure it was A: new England colonies.
This is why New England colonies were American settlers, The settlers hated the British and vice versa, And they mostly traded their goods money wasn't really used that much, the only people who would most likely buy this would be their neighbors and citizens.
I hope this helps.
An ineffective thesis statement on the causes of the French Revolution would be "The frivolous spending of the monarchs lead to the common man losing money." This would be ineffective as it fails to create a bigger picture and does not go into proper depth. More detail is better, as it leads to a more subjective thesis.
A, Slaves provided much of the labor on plantations that grew cash crops would be the answer I would go with. Most slaves worked in crop fields, and iron working didn't become prominent in the US until the industrial revolution about 10 years after the Civil War. I cannot say I'm 100% certain, but the others to me don't seem to make sense when looking at the situation.
