When a unit step voltage drives a lag network the output
Answer: Option
Explanation:
At t = 0 the capacitor behaves as a short-circuit and output voltage is 0. At t = ∞ capacitor behaves as an open-circuit and V0 = Vi.

Lag network means? Please explain.

Because lag network have R and C.
The capacitor at t=o will be short and at t= infinity will become battery means an open circuit. Exponentially function describe this nature of capacitor for the lag network.

Xc = 1/jwc which will give negative lagging phase.
