Option (A ) is correct.

Explanation:

susan is moving with constant velocity, so both the direction and magnitude of the velocity remains same. so the acceleration of susan =0. This is because an object gets accelerated when either the magnitude or direction of the speed changes.

now the force is given by

F= ma

F= force

m= mass

a= acceleration

Here a =0

so F= 0

so the net force on susan is zero.
