Answer:
The correct answer is D.
Explanation:
When a right triangle is inscribed inside a circle, the hypotenuse of the triangle goes through the diameter. The answer is obvious even from this fact.
But if continue to apply the conditions of the question, we can observe that even we'll have one right triangle and one right isosceles triangle because the triangles don't overlap. The triangles will intersect at the hypotenuse because both of them are right triangle where the hypotenuse is a diameter.
