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.
