A spectrometer gives the following reading when used to measure the angle of a prism.Main scale reading: $58.5$ degreeVernier scale reading: $09$ divisionsGiven that $1$ division on main scale corresponds to $0.5$ degree. Total divisions on the vernier scale is $30$ and match with $29$ divisions of the main scale. The angle of the prism from the above data is:

1. A
   $58.59^{\circ }$
2. B
   $58.77^{\circ }$
3. C
   $58.65^{\circ }$
4. D
   $59^{\circ }$
