Using the technique of radial velocity, the greater/larger the star's 'wobble', the the orbiting planet is. a) larger b) smaller c) neither; if a star wobbles, it does not have a planet orbiting it.

Neither; if a star wobbles, it does not have a planet orbiting it. This technique measures with great precision the radial speed of the movement of a star due to the existence of a planet. The most successful experiment was due to the use of the HARPS instrument (High Accuracy Radial velocity Planetary Search project) of the Geneva Observatory, coupled to the 3.6-meter telescope at the chair. Radial velocity is the velocity of an object along the line of sight of the observer, this is the component of the speed with which the object approaches or redirects the observer, even if it does not move exactly in the collision direction with the observer. It is perpendicular to the transverse velocity of the object.
