Radius of circle O plus the diameter of circle P => 5+3+3=11

it says circle P is on the circumference of Circle C thus we take the diameter of circle P and add up to the radius of circle O

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.
