Answer: c. Caused economic depression within the united states.
The Embargo Act of 1807 was a general embargo against France and Great Britain during the Napoleonic Wars. It was meant to be in retaliation for violating American neutrality by seizing American merchant ships.
The embargo, however, was a complete failure. It failed to significantly affect France and Great Britain, while creating an economic depression in the US. It continued until 1809, in the last days of Jefferson's presidency.
