D)The relationship cannot be determined from the information given.
OP is perpendicular bisector of a right isosceles triangle with two sides as \(r\) and the hypotenuse as \(\sqrt{2}r\)
OP bisects the base into two equal parts i.e. \(\frac{r}{\sqrt{2}}\)
Apply Pythagoras theorem to find the length of OP:
\(r^2 = (\frac{r}{\sqrt{2}})^2 + OP^2\)
\(OP = \frac{r}{\sqrt{2}}\)
Clearly, Col. A = Col. B
Hence, option C
