Absent P Waves on EKG? SVT or V Tach?

I had a test question yesterday on a cardiac test for nursing school. The question read, "Your patient's monitor shows ABSENT P waves with a heart rate of 200 bpm. What rhythm is this?" I put VTach because it said ABSENT P WAVES but my instructor says that it is SVT. I'm sorry, but SVT has P waves but are hidden in the QRS because the rate is so high. I believe the answer should be V Tach. Any help appreciated!!
