Choice A is the correct answer.

1. Roots: $x = 0$ and $x = -4$.
2. Region: Since it opens upward and we want $\geq 0$, we look for the outside tails.
3. Order: $-4$ is less than $0$.
4. Solution: Left of smaller root ($x \leq -4$) or right of larger root ($x \geq 0$).

Choice B is incorrect because that is where it is negative. Choice C is incorrect because it misses the left part. Choice D is incorrect because it misses the right part.
