Answer:

D. 256

Explanation:

Given

[tex]Instructions = 8\ bit[/tex]

Required

Determine the maximum number of output

To get the required value, we make use of the following:

[tex]Maximum = 2^n[/tex]

Where n is the bits of the opcode.

i.e.

[tex]n = 8[/tex]

Substitute 8 for n in [tex]Maximum = 2^n[/tex]

[tex]Maximum = 2^8[/tex]

[tex]Maximum = 256[/tex]

Hence, option D answers the question
