Options:
  • A $\mathrm{I}_2+\mathrm{I}_{\mathrm{g}}$
  • B $\mathrm{I}_{\mathrm{g}}$
  • C $\mathrm{I}_2-\mathrm{I}_{\mathrm{g}}$
  • D $\mathrm{I}_2$

The correct answer is: $\mathrm{I}_2$
As the bridge is balanced, no current will flow through the galvanometer. Hence, the current through the $40 \Omega$ resistor will be $I_2$.
