We can use the distributive property to simplify this expression.

I split this up into different parts--it helps me visualize better.

To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"

Then, "5(-2m + 2n)" becomes "-10m + 10n"

Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"

We can then simplify even further by combining like terms. The final expression is: C

Hope this helps!
