If 4 is a root, then a factor must be x - 4.
Only choices A and D have x - 4 as a factor.
Now look at the constant term of each binomial in the factorizations of choices A and D.
A.: -4, 4, 5
Their product is -80.
The constant term of the original polynomial is -40, so this factorization cannot be correct.
D.: -4, 2, 5
Their product is -40.
This is the correct factorization.
Answer: D.
