Inside $a$ super conducting ring six identical resistors each of resistance $R$ are connected as shown in figure. Imagine a battery of $emf$ $E$ between the point $0$ and $1$, with its positive terminal connected with $O.$
  • AThe current entering at $O$ is equally divided into three resistances.
  • Bthe current in the other three resistances $R_{12}, R_{13}, R_{23}$ is zero.
  • CThe resistances $R_{02}$ and $R_{03}$ have equal magnitudes of current while the resistance $R_{01}$ have different current.
  • DBoth $(A)$ and $(B)$
