Why is this answer wrong? Parabolas, directrix, tangent lines, lions and tigers oh my!

I do not understand why so many math experts would mark this answer wrong.
If you graph the parabola, they would have the directrix going through the middle of it. What am I not seeing here?

Thanks so much for all you do!

I take it that yours was the answer with five thumbs-down dumped on it? If the question refers to the tangent through the given point (which is anything but clear), then your response is correct. And yes, the other one has a parabola intersected by its own directrix. The only problem I see is your overly generous use of the phrase "math experts".
