A galvanometer of resistance $$20 ~\Omega$$ gives a deflection of 5 divisions when $$1 \mathrm{~mA}$$ current flows through it. The galvanometer scale has 50 divisions. To convert the galvanometer into a voltmeter of range 25 volt, we should connect a resistance of

A
$$1240 ~\Omega$$ in series.
B
$$2480 ~\Omega$$ in series.
C
$$2480 ~\Omega$$ in parallel.
D
$$20 ~\Omega$$ in parallel.
