Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
Option C would be the right one

Explanation:
From the question we are told that:
Side length s=1.13m
Left field strength 
Right field strength 
Front field strength 
Back field strength 
Top field strength 
Bottom field strength 
Generally, the equation for Charge flux is mathematically given by

Where
Theta for Right,Left,Front and Back are at an angle 90

Therefore
with respect to Right,Left,Front and Back
Generally, the equation for Charge Flux is mathematically also given by
Where

Therefore
