What is the value for the 32-bit register EAX after executing the mnemonic opcode/operand instruction MOVZX? (This mnemonic opcode/operand instruction converts 8-bits to 32-bits)
MOV EAX, 0 MOV AX, 0x54C9BF5 MOVZX EAX, AX
| a. | EAX= 004C9BF5 | |||||||||||||
| b. | EAX= 000C9BF5 | |||||||||||||
| c. | EAX= 00009BF5 | |||||||||||||
| d. | EAX= 000000F5

The hexadecimal data 36AB4CFD4CA2 is located in the real mode memory based on the little endian format using a register indirect addressing mode, If the register DI contains the value 0004H with a data segment DS value of 0001H and the mnemonic opcode/operand MOV AX, [DI] instruction executes, what will be the value stored into the register AX?
| a. | AX register is loaded with the data 36AB. | |
| b. | AX register is loaded with the data BA36. | |
| c. | AX register is loaded with the data AB9A. | |
| d. | AX register is loaded with the data AB36. |
