I think the correct answer is C
The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.

Sorry if this is not what you want me to do and I just threw a bunch of words at you.
Given that,
Mass of a boy = 50 kg
The coefficient of static friction = 0.68
To find,
Let us assume we need to find the maximum static friction between the boy and the ground.
Solution,
The formula for the maximum static friction between the two objects is given by :

Where
N is normal force
Substitute all the values,

Therefore, the maximum static friction between the boy and the ground is 340 N.
