Correct option is D
Displacement Reaction: In a displacement reaction, a more reactive element displaces a less reactive element from its compound.
Example: In Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s), zinc (Zn), being more reactive than copper (Cu), replaces copper in copper sulfate to form zinc sulfate.
Additional Information:
2AgCl(s) → 2Ag(s) + Cl₂(g): This is a decomposition reaction. It involves the breakdown of silver chloride (AgCl) into silver (Ag) and chlorine gas (Cl₂).
C(s) + O₂(g) → CO₂(g): This is a combustion reaction, where carbon reacts with oxygen to form carbon dioxide.
CaO(s) + H₂O(l) → Ca(OH)₂(aq): This is a combination reaction, where calcium oxide reacts with water to form calcium hydroxide.
