The Correct Option is D
Solution and Explanation
When chlorine gas is passed through slaked lime (Ca(OH)$_2$), it reacts to form bleaching powder (Ca(OCl)$_2$). This is a common reaction used in the production of bleaching powder.
The chemical reaction is:
\[
\text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{Ca(OCl)}_2 + \text{H}_2\text{O}
\]
