Correct answer: B

  1. We need to match the elements with their characteristic flame colours.

  2. Recall the standard flame test colours:

    • K\mathrm{K}K (Potassium) →\rightarrow→ Violet (or lilac)
    • Ca\mathrm{Ca}Ca (Calcium) →\rightarrow→ Brick red
    • Sr\mathrm{Sr}Sr (Strontium) →\rightarrow→ Crimson red
    • Ba\mathrm{Ba}Ba (Barium) →\rightarrow→ Apple green

  3. Now match with List II:

    • A. K\mathrm{K}K →\rightarrow→ II. Violet
    • B. Ca\mathrm{Ca}Ca →\rightarrow→ I. Brick Red
    • C. Sr\mathrm{Sr}Sr →\rightarrow→ IV. Crimson Red
    • D. Ba\mathrm{Ba}Ba →\rightarrow→ III. Apple Green

  4. Hence the correct matching is: A\!-II,\; B\!-I,\; C\!-IV,\; D\!-III

  5. Checking options:

    • Option A: Incorrect
    • Option B: Correct
    • Option C: Incorrect
    • Option D: Incorrect

Therefore, the correct answer is Option B.
