The phase difference between virtual voltage and virtual current for a wattless current will be:

90°

The correct answer is Option (1) → 90°

In an AC circuit, wattless current refers to a situation when the average power dissipated in the circuit is zero.

And, when the phase difference between voltage and current is 90°, the power dissipated in the circuit is 0. $[\cos 90° =0]$
