If the textbook is moving at a constant velocity, there must be a balance of forces acting on it. In this case, the force you are applying by pushing the book is balanced by frictional forces between the book and the table. This balance of forces results in the book maintaining a constant velocity without accelerating or changing direction. Therefore, choice B is the correct answer.
