List I (Substances) | List II (Element Present) |
(A) Ziegler catalyst | (I) Rhodium |
(B) Blood Pigment | (II) Cobalt |
(C) Wilkinson catalyst | (III) Iron |
(D) Vitamin B12 | (IV) Titanium |
Ziegler catalyst → Titanium
Blood pigment (hemoglobin) → Iron
Wilkinson catalyst → Rhodium
Vitamin B12 → Cobalt
Thus, the correct matching is:
A-IV, B-III, C-I, D-II
So, the correct answer is: Option (4)
