A strain gauge forms one arm of the bridge shown in the figure below and has a nominal resistance without any load as $$\,{R_s} = 300\Omega .$$ Other bridge resistance are $$\,{R_1} = {R_2} = {R_3} = 300\Omega .\,\,$$ The maximum permissible current through the strain gauge is $$20$$ $$mA.$$ During certain measurement when the bridge is excited by maximum permissible voltage and the strain gauge resistance is increased by $$1$$% over the nominal value, the output voltage $${V_0}$$ in $$mV$$ is A
$$56.02$$
B
$$40.83$$
C
