So option (C) is right.

|When R2 is opened there is no current flow in the circuit.
So terminal voltage = Source Voltage

|Dear sreeyush sudhakaran what you are saying it is applicable to parallel circuits why means voltage remains same in parallel circuits.
And in case of series circuits current remains same.
|Vikas said: (Mar 30, 2012)|
|Deqar Ravuteja Sreeyush is correct when circuit is open the V will be same as source V.|
|Kiran Hatti said: (Jul 20, 2012)|
|When circuit is open there will be no current, so voltage will be same as source voltage.|

|No KVL for this circuit. Because those resistors are in parallel form.
In parallel form resistors voltage drop is equal.
|Kreym said: (Jul 15, 2016)|
|This is not in the parallel form we are still in series circuits discussion.|

|The reason behind no current because in Series condition all the resistors have same amount of current flow through it so if r2 is open and other will not that's mean input voltage = output voltage.|
