A Series RL Circuit with Inductance L, Resistance R, and a Switch

Multiple Choice

A series RL circuit with inductance L, resistance R, and a switch is connected to an emf V. The switch had been connected to the closed position long enough for the current in the circuit to reach its maximum value. The switch is opened at $t = 0$ s. The graph that most likely shows the current in the circuit as a function of time is

A) A
B) B
C) C
D) D
E) E
