The correct answer is (a) True

For explanation: Tube drawing a kind of metal forming process which is very similar to bar drawing process, except the beginning of input material is a tube. This process is used to reduce the diameter, improve the surface finish and improve the dimensional accuracy of the metal tube. In this process, a mandrel may or may not be used, which mainly depends on the purpose.
