Correct answer: A

  1. Match each item in List-I with its function in List-II

    (A) AC generator

    • An AC generator converts mechanical energy into electrical energy.
    • So, (A)→(II)(A) \to (II)(A)→(II).

    (B) Galvanometer

    • A galvanometer is used to detect the presence of current in a circuit.
    • So, (B)→(I)(B) \to (I)(B)→(I).

    (C) Transformer

    • A transformer is used to change alternating voltage to a smaller or greater value.
    • So, (C)→(IV)(C) \to (IV)(C)→(IV).

    (D) Metal detector

    • A metal detector works on the principle of resonance in AC circuit.
    • So, (D)→(III)(D) \to (III)(D)→(III).

  2. Final matching

    (A)−(II),(B)−(I),(C)−(IV),(D)−(III)(A)-(II),\quad (B)-(I),\quad (C)-(IV),\quad (D)-(III)(A)−(II),(B)−(I),(C)−(IV),(D)−(III)

  3. Compare with options

    This corresponds to Option A.

  4. Comparison with stored correct answer

    • Derived answer: A
    • Stored correct answer: A
    • Hence, they agree.
