Answer:
B. The insistence of the first American governor to institute an English only policy upset Creole leaders.
Explanation:
Being in unfavorable conditions from the very beginning (paucity, isolation, an abundance of native cultures of Indigenous Indians, and later - Negro slaves, which were more accustomed to these conditions), Creoles tried to maintain their own ethno-cultural and cultural-religious integrity.
Their already aggressive attitude towards any encroachment on their secluded lifestyle and value system was aggravated after Louisiana became the eighteenth US state in 1812. This intensified the rivalry between Creole aristocrats and Americans, who began to settle in Louisiana already in the 18th century and perceived New Orleans to some extent the same as the frontier, as a place of unlimited enrichment opportunities.
There were also many Creole dialects, which more or less assimilated the linguistic features of the diverse cultures surrounding them, for example, the Antillean-Creole dialect. Finally, colonial French remained in a more or less pure form .
