In Craig v. Boren, the Court struck down Oklahoma's law which allowed 18-year old women to buy 3.2 beer, but required men to be 21 to purchase beer. What happens next?

(A) The law is void and any person of any age can buy beer. (B) Eighteen-year-old men are free to buy beer, but the Oklahoma legislature would be free to raise the age for everyone to 21. (C) The law remains enforceable as written until the Oklahoma legislature decides whether to raise the minimum age to 21 for everyone. (D) Eighteen-year-olds are free to buy beer, and any attempt by Oklahoma to raise the age to 21 for everyone would be unconstitutional
