Current lags voltage (and voltage leads current) when the inductive reactance is greater than the capacitive reactance.
That is only the case in one of your five options
the table below shows the values of the resistance, capcitive reactance and inductive reactance for five RCL circuits. in which circuit will the voltage lead the current?
Resistance capacitive inductive
reactance reactance
a)50 ohm 288ohm 244ohm
b)120 ohm 58 ohm 18 ohm
c)212ohm 314ohm 78 ohm
d)30 ohm 219 ohm 180 ohm
e)150 ohm 79 ohm 212ohm
