Answer 1

I think so bit A.press load is reduces

Answer 2

In case of sheet metal blanking, shear is provided on punches and dies so that the press load is reduced.

So, the right option for this answer would be option A i.e. "Press load is reduced".

Actually, this is a process of fabrication of the metal sheet and some part of the corresponding metal is removed from the overall metal.

This happens through the process of punching. on the other hand, the new metal which has been formed after removal of the old metal is termed as "blank".
