After executing MOV A, #0C3H followed by RL A, what is the value in A and the state of the Carry flag?
A=0x61, C=0 (arithmetic left shift preserving sign bit)
A=0x87, C=unchanged (RL rotates left without involving carry: 1100 0011 → 1000 0111, bit 7 wraps to bit 0)
A=0x86, C=1 (standard left shift operation with carry out)
A=0x87, C=1 (bit 7 shifted into carry flag)
