Since the given equation is a quadratic equation, it can have at most two solutions. In this case, the equation can be factored as 2x(x+4) = 0, which gives us two solutions x = 0 and x = -4. Therefore, the total number of solutions to the equation is two, making option C the correct answer.

Option A is incorrect because even though the equation has a zero on one side, the other side has an expression that can be factored and give a non-zero solution.

Option B is incorrect because, as explained earlier, the equation has two solutions.

Option D is also incorrect because, as mentioned before, the equation has only two solutions, not three.
