In the process of metal rolling operation, along the arc of contact in the roll gap there is a point called the neutral point, because

• A. on one side of this point, the work material is in tension and on the other side, the work material is in compression
• B. on one side of this point, the work material has velocity greater than that of the roll and on the other side, it has velocity lesser than that of the roll
• C. on one side of this point, the work material has rough surface finish and on the other side, the work material has very fine finish
• D. at this point there is no increase in material width, but on either side of neutral point, the material width increases
