- \( \text{NaBr} \)
- \( \text{CaI}_2 \)
- \( \text{KNO}_3 \)
- \( \text{NH}_4\text{Cl} \)

The Correct Option is D
Solution and Explanation
The reaction involved is:
\[2\text{NH}_4\text{Cl} + \text{MnO}_2 + 2\text{H}_2\text{SO}_4 \xrightarrow{\Delta} \text{MnSO}_4 + (\text{NH}_4)_2\text{SO}_4 + 2\text{H}_2\text{O} + \text{Cl}_2 \uparrow\]
In this reaction, chlorine gas (\( \text{Cl}_2 \)) is liberated, which has a greenish-yellow color.
