What are the contents of registers A and B after executing MOV A, #25, MOV B, #18, MUL AB?

A=0x01C2 (complete 16-bit result stored in A register)

❌

A=25, B=18 (operands unchanged because MUL requires separate instruction)

❌

A=0xC2 (low byte of product), B=0x01 (high byte of product), because 25×18=450=0x01C2

✅

A=0x01 (high byte), B=0xC2 (low byte), reversing the byte order

❌
