The correct answer is:
to pump out $\mathrm{CO}_{2}$
In a lime kiln, to get higher yield of $\mathrm{CO}_{2}$, the measure that can be taken is to pump out $\mathrm{CO}_{2}$. This will reduce the pressure of $\mathrm{CO}_{2}$ and reaction will shift in forward direction.
$$
\mathrm{CaCO}_{3} \stackrel{\text { Heat }}{\longrightarrow} \mathrm{CaO}+\mathrm{CO}_{2}
$$
