The centripetal force acting on a particle is given by F = mv2/r. If the centripetal force and mass are kept constant, increasing the radius of the particle's circular path will mean that the particle's velocity must decrease. Note that the question is asking about the radius of the particle's circular path, not just the radius of the particle.
