Correct answer: B

  1. We match each item in List I with the metal/element it is famously associated with.

  2. (a) Chlorophyll

    • Chlorophyll contains magnesium at its center.
    • So, (a)→(iv)(a) \to (iv)(a)→(iv).

  3. (b) Vitamin B12B_{12}B12​

    • Vitamin B12B_{12}B12​ is a cobalt containing compound.
    • So, (b)→(iii)(b) \to (iii)(b)→(iii).

  4. (c) Anticancer drug

    • A well-known anticancer drug is cisplatin, which contains platinum.
    • So, (c)→(ii)(c) \to (ii)(c)→(ii).

  5. (d) Grubbs catalyst

    • Grubbs catalyst is a ruthenium based catalyst.
    • So, (d)→(i)(d) \to (i)(d)→(i).

  6. Therefore, the complete matching is:

    (a)−(iv),(b)−(iii),(c)−(ii),(d)−(i)(a)-(iv),\quad (b)-(iii),\quad (c)-(ii),\quad (d)-(i)(a)−(iv),(b)−(iii),(c)−(ii),(d)−(i)

  7. Now compare with options:

    • Option A: incorrect
    • Option B: (a)−(iv),(b)−(iii),(c)−(ii),(d)−(i) (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)(a)−(iv),(b)−(iii),(c)−(ii),(d)−(i) ✔
    • Option C: incorrect
    • Option D: incorrect

Hence, the correct answer is Option B.
