Answer : The correct option is,
$Ca+ZnCO_3\rightarrow CaCO_3+Zn$

Explanation :

Displacement reaction : It is a chemical reaction in which a most reactive element displaces the least reactive element easily from its compound.

$A+BC\rightarrow AC+B$

In this, A is more reactive element and B is less reactive element.

The given balanced chemical reaction will be,

$Ca+ZnCO_3\rightarrow CaCO_3+Zn$

In this reaction, calcium displace the zinc element easily because calcium is more reactive element than the zinc.
