In the circuit shown, an ideal battery of EMF \(\varepsilon_0\) is connected to a switch \(S\), two identical resistors each of resistance \(R\), and an initially uncharged capacitor of capacitance \(C\).

At time \(t = 0\), the switch is closed. Consider the following four currents in the circuit:

• \(I_1\): the current through the battery at \(t = 0^+\)
• \(I_2\): the current through resistor \(R_2\) as \(t \to \infty\)
• \(I_3\): the current through capacitor \(C\) at time \(t = \tau\), where \(tau\) is the time constant of the circuit
• \(I_4\): the current through resistor \(R_2\) at \(t = 0^+\)

Which of the following correctly ranks the magnitudes of these currents from greatest to least?
