The correct answer is D. All of the following are examples of a four-year college except the Arapahoe Community College.
Explanation:
Community colleges are primarily public institutions of higher education that offer two-year university education (Associate degrees).
They are frequently referred to as Junior Colleges because they are for many a step towards longer subsequent academic courses, and also to distinguish them from Colleges which offer four-year courses. But the term "Community" is increasingly used to mark the regional roots of these institutions that usually attract students from the local community, and are most often financed by local taxes.
