A galvanometer has a resistance of 30 \[\Omega \] and a current of 2.0 mA gives full scale deflection. How will you convert this galvanometer into a voltmeter of 0.2 volt range?

A)  700\[\Omega \]. resistance should be connected parallel to the galvanometer.

B)  70 \[\Omega \] resistance should be connected parallel to the galvanometer.

C)  700\[\Omega \], resistance should be connected in series with the galvanometer.

D)  70 \[\Omega \] resistance should be connected in series with the galvanometer.
