There is no such thing as an obtuse right triangle. If one of the sides is 90degrees, both of the other angles must add up to 90 degrees, so in this situation, there can be no obtuse angles, therefore an obtuse right triangle is impossible to draw and doesn't exist.

C. No triangle has both a right and an obtuse angle, since the sum of these two angles alone is greater than 180 degrees.
