The figure shows three circuits with identical batteries, inductors, and resistors. Rank the circuits according to the current through the battery (i) just after the switch is closed and (ii) a long time later, greatest first

A.             (i) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\,\,({{i}_{1}}=0)\] (ii) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]
B.             (i) \[{{i}_{2}}<{{i}_{3}}<{{i}_{1}}\,\,({{i}_{1}}\ne 0)\] (ii) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]
C.             (i) \[{{i}_{2}}={{i}_{3}}={{i}_{1}}\,\,({{i}_{1}}=0)\] (ii) \[{{i}_{2}}<{{i}_{3}}<{{i}_{1}}\]
D.             (i) \[{{i}_{2}}={{i}_{3}}>{{i}_{1}}\,\,({{i}_{1}}\ne 0)\] (ii) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]
Answer» B.             (i) \[{{i}_{2}}<{{i}_{3}}<{{i}_{1}}\,\,({{i}_{1}}\ne 0)\] (ii) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]
