Get the required transfer function with help of voltage divider rule by replacing a capacitor with xC. After calculating the e0/ei, calculate the phase of this overall transfer function.

If the phase is positive then it will be lead compensator and of it is negative then it will be lag compensator.

In this particular case calculating the value of phase will give you a positive value which means it is lead compensator.
