What did the Supreme Court do in the case of Schechter Poultry Corporation v. United States?

B) It overturned the National Industrial Recovery Act, ruling that Congress had given too much power to the president and representing the growing opposition to the New Deal.
C) It decided that Schechter was involved in interstate, not local, trade and therefore need not change anything about its practices to adhere to the law.
D) It upheld the constitutionality of the second Agricultural Adjustment Act because it protected the "middle men" that processed food crops and warehoused commodities.
E) It prevented Roosevelt from going through the Second New Deal, even though he had already helped put together most of the policy for it.
