In the figure above, the circles with centers O and P have radii of 5 and 3 respectively, and have exactly one point in common. If a circle C (not shown) is drawns such that O is its center and P is on its circumference, what is the radius of circle C?

However it does not explicitly mention whether the circle P is on the circumference or the center of circle P is on the circumference. For that reason I cannot definitely state whose answer between me and you is correct,

There is no CIRCLE P in the question.....P is only point , which is center

IMO A - 8 Let the common point be M. OP (radius of circle C) = OM + MP 5+3 = 8

If O is the center of circle and point P lies on its circumference then radius will be OP which is equal to OP=OM+MP Hence 5+3 = 8 Option A is our winner.
