Answer :-
The person who is exerting 55N will move the box 20N to the right (option B).
Reason :-
- The total force by the two people in the left side is .. 17 N + 16N = 33N.
- So, the net force acting on the box is, 55N - 33N = 20N.
- The box will move towards the right because greater force is acting there.
