Answer

The current through the resistor $R$ in all three situations will be zero.

Work Step by Step

A long time after the switch is closed, the inductor acts like an ordinary wire. Since the resistance in the inductor is essentially zero, all the current will flow through the inductor and no current will flow through the resistors. The current through the resistor $R$ in all three situations will be zero.
