Which economic factor involved trade barriers between colonies?

• A. Trade barriers between colonies
• B. End of reciprocity with the United States
• C. End of free trade with Britain
• D. Need for railway to improve trade between colonies

Answer: (A)

Trade barriers themselves were the economic factor that shaped how colonies traded with each other. When colonies imposed duties, taxes, and restrictions on goods moving across borders, they effectively restricted markets, raised prices, and protected local producers. Those barriers directly influence intercolonial commerce, making them the key factor in this context.

End of reciprocity with the United States would shift external trade dynamics, not the internal barriers between colonies. End of free trade with Britain changes foreign trade relations rather than the intra-colony gatekeeping. Building a railway would be a response to trade flow issues, aiming to overcome barriers rather than being the barrier itself.
