Assertion (A): A line of length and short circuited at far end has an input impedance of infinity. Reason (R): A line of length and short circuited at far end behaves as a parallel resonant circuit.

• Both A and R are correct and R is correct explanation of A
• Both A and R are correct but R is not correct explanation of A
• A is correct but R is wrong
• A is wrong but R is correct
