Okay, here we have this:
Considering the provided expression, we are going to perform the requested operation, so we obtain the following:
[tex]\begin{gathered} (8-5i)^2+(8+5i)^2 \\ =-80i+64-25+80i+64-25 \\ =39+39 \\ =78 \end{gathered}[/tex]
Finally we obtain that the correct answer is the option A.
