The statement that best describes the impact of the Civil War on the economy of Texas is: "The Civil War disrupted trade between Texas and its trading partners."
During the Civil War, Texas faced significant disruptions in trade due to blockades, the destruction of infrastructure, and shifts in economic focus, leading to a difficult economic period. While there were other effects, such as changes in crop production, the disruption of trade is a key and direct consequence of the war's impact on the Texas economy.
