The correct answer is
- Correct answerAA-III, B-IV, C-I, D-II
- BA-IV, B-III, C-II, D-I
- CA-III, B-IV, C-II, D-I
- DA-II, B-IV, C-I, D-III
Solution
Peroxides are good oxidizing agents so $\mathrm{Na}_2 \mathrm{O}_2$ is used as an oxidizing agent.
Heavy water $\mathrm{D}_2 \mathrm{O}$ is used in nuclear reactors as moderator. Cesium (Cs) metal is used in photoelectric cells due to its low ionization energy.
$\mathrm{Mg}(\mathrm{OH})_2$ is used as an antacid by ne tralizing the acidic substances.
Thus, $\mathrm{A} \rightarrow$ III, $\mathrm{B} \rightarrow$ IV, $\mathrm{C} \rightarrow$ I, D $\rightarrow$ II
Hence, the correct answer is option: 'A'.
