Solution
The correct option is B QR
It is given that the triangle is a right-angled at point P.
So, the two arms of the right angle will be the two sides containing P as one of their vertices.
Therefore, PQ & PR are the two arms of the right angle and the third side i.e. QR will be the hypotenuse of the triangle.
Since we know that the hypotenuse is the longest side in a right-angled triangle, we can say that the longest side will be QR.
