Economic conflict(s) leading to the Civil War __________________________.

A) were over tariffs and the extension of slavery into the new territories
B) was the growing free trade with England
C) was Abraham Lincoln freeing the slaves
D) None of the choices are true

The economic conflicts leading to the Civil War were primarily over tariffs and the extension of slavery into the new territories. The North favored protective tariffs to protect its industries, while the South opposed them since it relied heavily on exporting raw materials. Additionally, the North opposed the extension of slavery into the new Western territories, while the South sought to expand slavery to support its agricultural economy. These economic differences, along with social and political tensions, ultimately led to the outbreak of the Civil War.
