Solution

The correct option is C
Simple displacement

Correct answer is option c) Simple displacement
Definition of Simple displacement reaction
When an element displaces another element in a compound is called simple displacement reaction.
When Zinc react with dilute sulphuric acid to form zinc sulphate and hydrogen gas
Zn(s)+ H₂SO₄(aq) $\to$ ZnSO₄(s)+ H₂(g)
Here zinc displaces, hydrogen from sulphuric acid
Explanation of incorrect answer
A) Double decomposition
It is a type of decomposition reaction in which products obtained by interchanging the ions of reactants.
For example
ZnSO₄(aq₎+ NaOH(aq) $\to$ Zn(OH)₂(aq)+ Na₂SO₄(aq)
B) Direct synthesis
A reaction in which two or more simpler substances combine to form a compound is called direct synthesis
For example. Potassium and chlorine react to form potassium chloride
2K(s)+Cl₂(g) $\to$ 2KCl(s)
D) Neutralization
When an acid react with base, a salt and water is formed. This process is called neutralisation reaction
NaOH(aq) + HCl (aq) $\to$ NaCl(s) + H₂O(l)
Base Acid Salt water
E) Decomposition by acid
When a compound dissociates into simpler substance is called Decomposition reaction
H₂O(l) $\to$ H₂(g)+O₂(g)
