In an RLC circuit, the maximum current occurs when the capacitor is fully charged and the inductor is fully discharged. This maximum current can be calculated using the formula I = V/R where V is the voltage across the circuit and R is the resistance of the circuit.

However, to find the average current, we need to take into account the fact that the current in the circuit varies with time due to the charging and discharging of the capacitor and inductor.

The average current over a cycle in an RLC circuit is equal to the RMS current. For an RLC circuit, the RMS current can be calculated using the formula:

Irms = Imax / √(2)

where Imax is the maximum current.

Substituting Imax = 1A, we get:

Irms = 1 / √(2) = 0.707 A

Therefore, the average current in the RLC circuit is 0.707 A or approximately equal to 1/2 A. Hence, the correct answer is option C.
