Hint:

Haemoglobin contains Fe while Chlorophyll contains Mg.

Answer 1

The Correct Option is D

Concept:
Many biologically important compounds contain characteristic metal ions.
Step 1:
Haemoglobin contains iron ion. \[ A \rightarrow II \]
Step 2:
Chlorophyll contains magnesium ion. \[ B \rightarrow IV \]
Step 3:
Vitamin \(B_{12}\) contains cobalt. \[ C \rightarrow I \] Cis-platin contains platinum. \[ D \rightarrow III \]
Step 4:
Final matching: \[ A-II,\quad B-IV,\quad C-I,\quad D-III \] \[ \boxed{\text{Correct Option = (4)}} \]
