Correct answer: D

  1. We match each catalyst with its well-known industrial process.

  2. Identify each catalyst-process pair:

    (A) TiCl3\mathrm{TiCl_3}TiCl3​

    • This is associated with Ziegler–Natta polymerization.
    • So, A→(ii)A \to (ii)A→(ii)

    (B) PdCl2\mathrm{PdCl_2}PdCl2​

    • This is used in the Wacker process.
    • So, B→(i)B \to (i)B→(i)

    (C) CuCl2\mathrm{CuCl_2}CuCl2​

    • This is used in Deacon's process.
    • So, C→(iv)C \to (iv)C→(iv)

    (D) V2O5\mathrm{V_2O_5}V2​O5​

    • This is the catalyst in the Contact process.
    • So, D→(iii)D \to (iii)D→(iii)

  3. Therefore, the complete matching is:

(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)
  1. Compare with the given options:
  • This matches Option D.
  1. Comparison with stored correct answer:
  • Stored correct answer = D
  • Derived answer = D
  • Hence, they agree.
