In the arrangement shown in figure when the switch \( S_{2} \) is open, the galvanometer shows no deflection for \( l=L / 2 \). When the switch \( S_{2} \) is closed, the galvanometer shows no deflection for \( l=5 L / 12 \). The internal resistance \( (r) \) of \( 6 \mathrm{~V} \) cell, and the \( \operatorname{emf} E \) of the other battery are respectively
(a) \( 3 \Omega, 8 \mathrm{~V} \)
(b) \( 2 \Omega, 12 \mathrm{~V} \)
(c) \( 2 \Omega, 24 \mathrm{~V} \)
(d) \( 3 \Omega, 12 \mathrm{~V} \)
