A series combination of L and R is connected to a battery of emf E and negligible internal resistance, then the final value of AC current depends upon:

Explanation

In a series R-L circuit connected to a DC battery, the final value of the current is determined by the battery's emf (E), the resistance (R), and the inductance (L). When the circuit reaches a steady state, the inductor behaves like a short circuit, and the current is determined by Ohm's law, I = E/R. However, during transient states, the inductor affects the time it takes to reach this steady state. Therefore, all three components-L, R, and E-play a role in determining the final current. Option A is incorrect because it ignores the battery's emf, Option B neglects the resistor, and Option C disregards the inductor's effect.
