Concept:French colonial policy of assimilation aimed to make African subjects adopt French language, culture, law, and citizenship.
Explanation:The French operated assimilation most successfully in the Four Communes of Senegal: Saint-Louis, Dakar, Goree, and Rufisque.
The people of these communes, called *originaires*, were granted full French citizenship with voting rights and representation in the French parliament.
Blaise Diagne, an African from Goree, was elected as a deputy to the French National Assembly in 1914, proving the success of the policy there.
Goree was a major centre where the policy was actually practised, far more than in any territory in Togo, Mali, or Ivory Coast.
Lome, Bamako, and Abidjan were more typical of French colonies where the policy remained largely theoretical or faced strong resistance.
Thus, among the given options, Goree best fits the description of a place where assimilation was successfully operated by the French.
Answer:B. Goree
