Assertion: Resonance phenomenon is exhibited by a circuit only, if both L and C are present in the circuit.
Reason: Voltage across L & C does not cancel each other and the current amplitude is `V_m'/' R`, the total source voltage appearing across R causes resonance.
Options:
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false and R is also false.
