The correct answer is A
California v. Cabazon Band of Mission Indians was a US Supreme Court landmark decision issued in 1987. It abolished laws which restricted gaming and gambling on Indian reservations. States desired to control gaming in reservations but this decision concluded that Indian gambling could only be restricted in states where all gaming activities were deemed criminal according to state law. It was considered unconstitutional, that the states tried to limit only certain type of gambling activities and not others.
