When was the Civil Code’s name changed to the Napoleonic Code?

The correct option is D 1807
Napoleon, during his regime, introduced common laws that would apply to everyone in the empire. The Conseil d’Etat or the Council of State created these uniform laws. On 21 March 1804, the Council consolidated all the laws into a single body of law called the Code Civil des Francais or the Civil Code of 1804. In Napoleon’s honour, the Civil Code’s name was changed to the Napoleonic Code in 1807.
