Solution

The correct option is C drops to zero
If you remove the salt bridge, the circuit of the voltaic cell will be cut and the voltage will go to zero instantly.
Opening or cutting the circuit by removing the salt bridge stops all Galvanic chemical reactions instantly. There will be no 'stop working after some time', the cell will cease to operate the instant the circuit is cut.
