Answer:

B

Explanation:

its 1

for those of you that don't understand, when you multiply a complex number by its multipicatuive identity, in this case -4+8i, you would multiply both the top and the bottom by -4-8i which is actually the value one since we cannot actually change the whole value of the number. By multiplying it by "1" we get the same value just without the imaginary number .
