Answer:
D) The majority's interests should be offset with measures that protect regional minority interests.
Explanation:
John C. Calhoun proposed the concurrent majority in the 19th century to defend slavery. Protecting regional minority interests should offset dominant interests. This would ensure that the minority's concerns are considered and that there is a power balance. Calhoun warned that if southern interests weren't preserved, northern states could outvote them on any subject. This would render the South impotent and end slavery. The concurrent majority helped sustain slavery despite mounting resistance. Slavery was abolished in the U.S.
