You neglected to share the list of answer choices that you have,
so there's no way for anybody to help you select the correct one.
You just said that the object is moving with constant velocity.
That tells us right away that the object has no acceleration,
which in turn tells us right away that the net force on the object
is Zero. Taken as a group, all of the forces that may be acting
on the object are 'balanced'. They add up to zero, and have the
same effect on the object as if no forces acted on it at all.
