$\large\boxed{B). \,41}$

Step-by-step explanation:

In this question, we would be plugging in the given numbers to the right variables and solving from there.

We know that:

x = 4y = 5

Our equation is:

6(x^2 -y) - y^2

When you plug in the numbers, your equation should look like this:

6(4^2 -5) - 5^2

Now, you solve:

$6(4^2 -5) - 5^2\\\\\text{Lets start with the number inside the parenthesis}\\4^2\,\text{is the same as 4*4}\\\\6(16 -5) - 5^2\\\\6(11) - 5^2\\\\66-5^2\\\\5^2\,\text{is the same as 5*5}\\\\66-25\\\\\text{Finish by subtracting}\\\\41$

When you're done solving, you should get 41.

This means that B). 41 would be the correct answer.

I hope this helped you out.Good luck on your academics.Have a fantastic day!
