Best answer
Right option is (a) True

The explanation: The stretch forming process is generally performed by using a hydraulic operated ram. In this process, first a single form block is used along with the gripping jaws, and then the metal is gripped and stretched by applying high tensile forces until it deforms plastically. And then the sheet metal is bent and rolled around a form block.
