The Correct Option is D

Solution and Explanation

(P) Mg(HCO3)2+2Ca(OH)2Mg(OH)2+2CaCO3+2H2O\text{Mg(HCO}_3\text{)}_2 + 2\text{Ca(OH)}_2 \rightarrow \text{Mg(OH)}_2 + 2\text{CaCO}_3 + 2\text{H}_2\text{O} 
(Q) BaO2+H2SO4H2O2+BaSO4\text{BaO}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{H}_2\text{O}_2 + \text{BaSO}_4
(R) Ca(OH)2+MgCl2Mg(OH)2+CaCl2\text{Ca(OH)}_2 + \text{MgCl}_2 \rightarrow \text{Mg(OH)}_2 + \text{CaCl}_2
(S) BaO2+2HClBaCl2+H2O2\text{BaO}_2 + 2\text{HCl} \rightarrow \text{BaCl}_2 + \text{H}_2\text{O}_2
(T) Ca(HCO3)2+Ca(OH)22CaCO3+2H2O\text{Ca(HCO}_3\text{)}_2 + \text{Ca(OH)}_2 \rightarrow 2\text{CaCO}_3 + 2\text{H}_2\text{O}
I → Q

II → R

III → S

IV → P

Option (D) is correct.
