F is force
m is mass
a is acceleration
Now, Force is directly proportional to the acceleration and mass.
Thus, the higher the mass, the greater the force.
Thus, the object that will require the most force is the one that has the highest mass.
Looking at the options, the one with the highest mass is option D.
