Identify the correct statements about the mechanism of chip formation in machining:
I- The formation of the chip influences factors such as tool wear, cutting forces, heat generated in machining, penetration of the cutting fluid, among others.
II- The cutting of metals involves concentrated shear along a plane called the shear plane.
III- The angle between the shear plane and the cutting direction is called the shear angle.
IV- The lower the exit angle of the tool, the greater the contact length between the chip and the tool exit surface and the greater the adhesion zone.
V- The formation of the chip is a periodic phenomenon.
VI- The chip can assume different shapes, such as ribbon and pieces.

a) I, II, III, IV, V and VI are correct.
b) I, II, III, IV and V are correct.
c) II, III, IV, V and VI are correct.
d) I, III, IV, V and VI are correct.
