12. You are designing an ALU that must support the rotate-through-carry left (RCL) operation on 32-bit registers. If the current CF = 1 and the operand is 0x80000000, what are the new value of the register and the new carry flag? (A) 0x00000000, CF=0 (B) 0x00000000, CF=1 (C) 0x00000001, CF=0 (D) 0x00000001, CF=1 (E) 0x00000003, CF=1
