we have two circles \(c1\) and \(c2\).
we also have two \(segments\) that are equal PR and QR and \(length\) PR and QR are equal too
However, we cannot conclude that \(P\) and \(R\) are the centre of the circles \(c1\) and \(c2\)
nor can we derive the radius from the information given.
We do need the radius to find the circumference of the circle.
option D

It cannot be concluded from the image that P and Q are centers of the respective circles. hence we do not know radii of the circles.
