Resistance of a voltameter is \[2\,\Omega ,\] it is connected in series to a battery of 10 V through a resistance of \[3\,\Omega \]. In a certain time mass deposited on cathode is 1 gm. Now the voltameter and the \[3\,\Omega \] resistance are connected in parallel with the battery. Increase in the deposited mass on cathode in the same time will be

• A.            0    
• B.            1.5 gm
• C.            2.5 gm                                    
• D.            2 gm
