Answer #1

Solution:

B. Direct

Explanation:

C1 F2 1C

Binary of this instruction:

1100 - 0001 - 1111 - 0010 - 0001 - 1100

in assembly to know the addressing mode:

1100 - raaa - 1111 - 0010 - 0001 - 1100

aaa = 001 -> addressing mode = Direct

Note: you can refer the following image for the reference:
