The correct answer is C It impacted U.S. trade more negatively than French or British trade.
The Embargo Act of 1807 was intended to pressure Britain and France into respecting U.S. neutrality during their ongoing conflict. However, it severely restricted American trade and had a more detrimental effect on the U.S. economy compared to the economies of Britain and France. As such, it led to widespread dissatisfaction and was ultimately ineffective in achieving its goals, contributing to its failure.
