HELP OR I WILL FAIL Why did the French reinstate the Code Noir after gaining Louisiana from Spain?

to establish restrictions on the slave trade
to allow for the expansion of slavery
to reduce the chance of a revolt by enslaved people

to establish restrictions on the slave trade

Explanation:

The Code Noir defined the conditions of slavery in the French colonial empire, restricted the activities of free Negroes, made Roman Catholicism compulsory, and ordered all Jews out of France's colonies.

the noble might have thought that the system was far because they had lot of things and riches and the serf would have thought that the feudal system was un fair because of the way they were treated.
