Answer : The correct option is, [tex]Ca+ZnCO_3\rightarrow CaCO_3+Zn[/tex]
Explanation :
Displacement reaction : It is a chemical reaction in which a most reactive element displaces the least reactive element easily from its compound.
[tex]A+BC\rightarrow AC+B[/tex]
In this, A is more reactive element and B is less reactive element.
The given balanced chemical reaction will be,
[tex]Ca+ZnCO_3\rightarrow CaCO_3+Zn[/tex]
In this reaction, calcium displace the zinc element easily because calcium is more reactive element than the zinc.
