Answer: a. Restored the church, but had a clear separation of church and state agreement
Step-by-step explanation:
During the French Revolution, the Catholic Church lost a lot of its power in France on account of it having supported the Monarchy. Properties were seized from the Church and priests were expelled.
This ended in 1801 with the Concordat of 1801 signed between Napoleon and the Catholic Church. The Church was restored but the state was to be separate from it and religious freedom was to be practiced across the empire.
