Solution

The correct option is C guillotine
guillotine,
The machine used is called a squaring shear, power shear, or guillotine.

Shearing machines are multipurpose devices used in the cutting of alloys and other sheet metal. Some shearing machines use a scissor-like, angular shear action to cut metal into sheets or strips. Other, larger machines use a straight shear action with the blade fixed at an angle as opposed to the angular movement.
