Answer :
Final answer:
The sum of forces acting on Chuck is 108 N.
Explanation:
The sum of forces acting on Chuck can be determined by using Newton's second law, which states that the net force on an object is equal to its mass multiplied by its acceleration. In this case, since Chuck is standing motionless, his acceleration is zero. Therefore, the net force acting on him is also zero. So, the correct option is:
d) 108 N
