The correct answer is (b) False

For explanation: Shearing operations like blanking or punching basically includes cutting of metal sheet, which does not required in deep drawing process. In deep drawing, the flat section of the metal sheet under the holding plate moves towards the die axis and then bending occurs over the die profile. After bending, the metal sheet unbends to flow in downward direction along the side wall.
