After executing the following 16-bit left shift sequence on value 0x8042 (stored as 30H=80H, 31H=42H), what is the final 16-bit result? CLR C, MOV A, 31H, RLC A, MOV 31H, A, MOV A, 30H, RLC A, MOV 30H, A

Question

Answer

0x0084 with C=0 (simple shift with no overflow)

Answer

0x8042 with C=0 (unchanged because RLC preserves the value)

Answer

0x0084 with C=1 (shifted left once: 1000 0000 0100 0010 → 0000 0000 1000 0100, bit 15 went to carry)

Answer

0x1084 with C=0 (complete 17-bit result stored in 16 bits)
