Match List I with List II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{A.} & \text{AC generator} & \text{I.} & \text{Presence of both L and C} \\ \hline \text{B.} & \text{Transformer} & \text{II.} & \text{Electromagnetic induction} \\ \hline \text{C.} & \text{Resonance phenomenon to occur} & \text{III.} & \text{Quality factor} \\ \hline \text{D.} & \text{Sharpness of resonance} & \text{IV.} & \text{Mutual inductance} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (C) A-II, B-IV, C-I, D-III
AC generator works on electromagnetic induction (II); transformer on mutual inductance (IV); resonance needs both $L$ and $C$ (I); its sharpness is measured by the quality factor (III).
