Is it sensible to say that Adam Smith's central idea -- that economic power comes from lots of people participating in the marketplace of a stable, law-abiding, urbanized society linked by roads and canals -- had greater relevance to the economic development of the North than to the South, where markets, and cities, and infrastructure, remained comparatively underdeveloped?

a
No, because Adam Smith was mainly interested in Scottish independence from a brutal English occupation.

b
No, because Adam Smith was mainly concerned with preserving the privileges of aristocrats.

c
Yes because Smith's main focus was on preserving the rights of the individual firm in the marketplace, and regarded government intrusion in the marketplace as inevitably leading to intrusions on the rights of individuals.

d
No, because Adam Smith didn't think through the consequences of his theories in light of changes in energy production (i. e., the change from old-style solar power to fossil-fuel power).
