Given the lоcаtiоn mаrked with the dоt in the stаr radial velocity curve below (on the left-hand side), at which point (A-D) would the planet be located at this time (on the right hand-side figure)? (Note1: by convention, the radial velocity is negative when the star moves toward the observer on Earth. Note2: both star and planet move counterclockwise. Note3: the radial velocity refers to the star, but the question asks about the location of the planet.)
