Doubt from Inductors

#1

#2

Option A) is the right Answer because for a long time this circuit will behave as a open circuit so there will be no current in the circuit so point A is at higher potential of 12 V.

#3

If you are still confused then first study the properties of inductor when it is connected to a potential difference,how it behaves at t=0,and at long time.
Then you will be able to solve these type of questions.
