a. junior colleges.
b. four-year colleges.
c. community colleges.
d. the college board.

D. College Board

Explanation:

The correct answer is D. The College Board

Explanation:

Dual enrollment means you can enroll in two institutions at the same time, this is common in high school students who enroll in colleges to obtain credits. In this way, dual enrollment allows high school students to take classes they would have in college which helps them to make a transition, and also obtain credits to graduate learning. These courses are offered mainly by colleges including junior colleges, community colleges, and even four-year colleges although this includes only introductory courses.

However, dual enrollment is not offered by the college board, because this institution, only offers preparation for exams as well as advanced placement (AP) courses that are not the same as dual enrollment because students do not take college classes.
