The correct answer is B. Rural colleges
Explanation
Colleges are educational institutions that offer higher education programs, undergraduate programs or similar training programs for people who have already complete basic education levels. In the case of rural colleges this are colleges with the same objectives that regular colleges, but that are located in rural areas or isolated areas usually far from cities and where people from small population or towns who live in nearby areas go to, due to this rural colleges have relatively few students in comparison to colleges located in cities. Thus, colleges that are located in largely isolated areas with small populations are called rural colleges.
