What was the most important difference between the stand of the National Assembly and the National Convention?

Correct answer: The National Assembly hesitated and the National Convention abolished slavery in 1794

The governing concept is the changing revolutionary policy toward slavery. The National Assembly did not immediately abolish slavery because colonial plantation wealth and commercial interests influenced political decisions. Later, under the National Convention, slavery was abolished in French colonies in 1794, although this policy was subsequently reversed under Napoleon before final abolition in 1848. Option A captures the contrast required by the question. Option B confuses the National Assembly with the later date of final abolition, while C and D contradict the historical development. Therefore A is correct.
