m is mass of planet
R is distance from sun
F = G Msun m/R^2
look for maximum of
m / R^2

....; but is distance goes up, force goes DOWN

I suspect Jupiter is correct because m is more or less proportional to planet radius CUBED while 1/R^2 is not so strong but not enough information is given to know. You must compare m/R^2.
