b)the development of factories
c)an increase in immigration
d)the formation of enclaves

the answer is the formation of enclaves

d) The formation of enclaves

Explanation:

The main origins of the enclaves in cities were the segregation of immigrants. Immigrants in America were not completely accepted by society, so immigrants settled in neighborhoods such as Chinatowns, a place where the immigrants would live maintaining their culture but completely separated from the rest of the city.

The enclaves increased a lot after the 1965 Hart-Cellar Immigration Act because of the influx of new immigrants from other countries such as the Philippines, Korea, India/South Asia, and Vietnam. Enclaves are present in almost every major metropolitan area.
