Detailed Solution

Concept: A magnetic flux produced by an inductor is proportional to the current that travels through it. However, an inductor opposes the rate of change of current flowing through it instead of a capacitor, which opposes a change in voltage across its plates because of the accumulation of self-induced energy inside its magnetic field.
Given the:
The magnitude of the current flowing through the inductor is

.
The current flowing through the capacitor is

.
The figure shows the circuit of the inductor with capacitor capacity C and inductance L.
Let me get the current drawn from the source
In the LC circuit, the slope of the capacitor is

.
The inductance of the power supply has a delay of

. This description of the current through the inductor lags

with respect to the capacitor or the current through the capacitor.
Next, the magnitude of the current drawn from the source is given as follows:

Replace the value,

Therefore, the required current from the source is 1.2A .
Hence, the correct option is 3.
