When both the jaws touch each other, the Vernier scale shifts to the left of zero of the main scale in such a way that 4th4^{th} Vernier division coincides with a division of the main scale. If this Vernier calliper measures the length of a wire to be 1 cm, the actual length of the wire is:

A

0.96 cm

B

1.00 cm

C

1.04 cm

D

0.60 cm
