(C) The given circuit can be analyzed by applying Kirchhoff's Voltage Law $(KVL)$ to different loops.Let the nodes be labeled as shown in the diagram.Applying $KVL$ in the upper loop (containing $E_1$,$r_1$,and $R$):Starting from node $E$ and moving clockwise through $F, B, A$ and back to $E$:Moving through the branch $EF$ (containing $E_1$ and $r_1$): The potential changes by $+E_1 - i_1 r_1$.Moving through the branch $AB$ (containing $R$): The potential changes by $-(i_1+i_2)R$.Summing these potential changes to zero: $E_1 - i_1 r_1 - (i_1+i_2)R = 0$.This can be rearranged as $E_1 - (i_1+i_2)R - i_1 r_1 = 0$.Comparing this with the given options,it matches option $(c)$.
