Assertion (A): When excited by a unit step voltage, an inductor behaves as open circuit at t = 0.

Reason (R): Inductance has the property of inertia.

Both A and R are true and R is correct explanation of A
Both A and R are true and R is not the correct explanation of A
A is true but R is false
A is false but R is true
