\[A50\Omega \]resistance is connected to a battery of 5V. A galvanometer of resistance \[100\Omega \]is to be used as ammeter to measure current through the resistance, for this a resistance \[{{r}_{s}}\] is connected to the galvanometer. Which of the following connections should be employed if the measured current is within 1% of the current without the ammeter in the circuit ?   JEE Main Online Paper (Held On 09 April 2016)

A) \[{{r}_{s}}=0.5\Omega n\]parallel with the galvanometer

B) \[{{r}_{s}}=0.5\Omega \]in series with the galvanometer

C) \[{{r}_{s}}=1\Omega \] in series with galvanometer

D) \[{{r}_{s}}=1\Omega \] in parallel with galvanometer
