Your que is wrong
Current is not lead in circuit contains inductor only but lagging by a phase of pi/2
In circuit containing capacitor only current leads by a phase of pi/2 from boltage

Hey !!
If V = V₀ sinωt
q = CV = CV₀sinωt
∴ I = dq/dt = ωCV₀ cosωt
(or) I = ωCV₀ sin(ωt + π/2)
So, the current leads the applied voltage in phase by π/2
Good luck !!
