If the net force acting on any object is zero, then the object's acceleration

is zero. That means that the object is not speeding up or slowing down,

and the direction of its motion isn't changing. This is another way of saying

that its velocity is constant.

Now, if the object started out stationary as the question says, and the

net force on it is zero, then it can't get going, and it remains stationary.

The acceleration is zero, and so is the velocity. (choice-A)
