Two full turns of the circular scale of ...

Two full turns of the circular scale of a screw gauge cover a distance of 1mm on its main scale. The total number of divisions on the circular scale is 50. Fuerther, it is found that the screw gauge has a zero error of `-0.03` mm, while measuring the diameter of a thin wire , a student notes the main scale reading of 3 mm and the total no. of circular scale divisions in line with the main scale as 35. The diameter of the wire is

A

B

`3.73 mm`

C

`3.67 mm`

D

`3.38 mm`
