B. 64
Explanation:
You forgot to write the expression, but I found it and I've written in a comment under question. This expression is:
[tex]4(x-y)^4[/tex]
To evaluate this expression for [tex]x=-2 \ and \ y=-4[/tex], just substitute these values into the expression and solve:
[tex]4(x-y)^4 \\ \\ =4(-2-(-4))^4 \\ \\ =4(-2+4)^4 \\ \\ =4(2)^4 \\ \\ =4(16) \\ \\ \boxed{=64}[/tex]
