Which planets have the largest accelerations of gravity?
a. mercury, venus, earth
c. pluto, venus, jupiter
b. jupiter, neptune, saturn
d. all planets have the same acceleration of gravity.

b. Jupiter, Neptune and Saturn

Explanation:

As acceleration of gravity is described in terms of size and volume of the celestial bodies, Planets in option b that is Jupiter, Neptune and Saturn will have largest acceleration of gravity.

Greater the volume and density of the body, more will be the mass hence more acceleration of gravity will be there.

If we compare the acceleration of gravity of given planets, we will come to know that Jupiter has acceleration of gravity equal to 24.79 m/s², Saturn has 10.44 m/s² and Neptune has 11.15 m/s². This combination is more as compare to other three options.

i think the answer is a, hope this is right, that would be my best guess.
