Solution

The correct option is B $C a O$ is the limiting reagent and $200$ gm of $C a C O_{3}$ are formed
The given reaction is,
$C a O + C O_{2} \to C a C O_{3}$
Again,
132 gm of carbon dioxide = $\frac{132}{44} = 3 m o l$
128 gm of calcium oxide = $\frac{128}{64} = 2 m o l$
So $C a O$ is the limiting reagent.
From the stoichiometry of the reaction $C a C O_{3}$ formed $= 2 m o l$
Again, $2$ mol of $C a C O_{3} = 2 \times 100 = 200 g m$
