Consider a Vernier callipers in which each `1cm` on the main scale is divided into `8` equal divisions and a screw gauge `5` divisions of the Vernier scale coincide with `4` divisions on the main scale and in the screw gauge, one complete rotation of the circular scale moves it by two divisions on the linder scale. Then:

A

If the pitch of the screw gauge is twice the least count of the Vernier callipers, the least cow1t of the screw gauge is 0. 01 mm.

B

If tlie pildrnf lite screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.005 mm.

C

If the least count of the linear scale of the screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.01 mm.

D

If the least count of the linear scale of the screw gauge is twice the least count of the Vernier callipers, the least count of the screw gauge is 0.005 mm.
