The diagram given below shows a solenoid carrying time varying current \( l=l_{0} t \). On the axis of the solenoid, a ring has been placed. The mutual inductance of the ring and the solenoid is \( M \) and the self inductance of the ring is \( L \). If the resistance of the ring is \( R \) then maximum current which can flow through the ring is
(1) \( \frac{(2 M+L) l_{0}}{R} \)
(2) \( \frac{M I_{0}}{R} \)
(3) \( \frac{(2 M-L) I_{0}}{R} \)
(4) \( \frac{(M+L) I_{0}}{R} \)
