Correct answer: C

  1. Match each item in List I with the correct concept in List II

A. AC generator

An AC generator works on the principle of electromagnetic induction.

  • So, A→IIA \to \text{II}A→II

B. Transformer

A transformer works on the principle of mutual induction between primary and secondary coils.

  • So, B→IVB \to \text{IV}B→IV

C. Resonance phenomenon to occur

In an AC circuit, resonance occurs in an LCR circuit, so both inductance LLL and capacitance CCC must be present.

  • So, C→IC \to \text{I}C→I

D. Sharpness of resonance

The quality factor measures the sharpness of resonance.

  • So, D→IIID \to \text{III}D→III
  1. Final matching
A−II,B−IV,C−I,D−IIIA-\text{II},\quad B-\text{IV},\quad C-\text{I},\quad D-\text{III}A−II,B−IV,C−I,D−III
  1. Compare with options

This corresponds to Option C.

  1. Comparison with stored correct answer

Stored correct answer is C, which matches our derived answer.
