Match the following compounds with their uses:

• A. A-III, B-II, C-I, D-IV
• B. A-IV, B-II, C-I, D-III
• C. A-III, B-I, C-II, D-IV
• D. A-IV, B- , C-II, D - III

Hint:

Memorize common uses of inorganic compounds such as O$_3$, SO$_2$, H$_2$SO$_4$, and PH$_3$.

Answer 1

The Correct Option is A

O$_3$ acts as a germicide (A-III). SO$_2$ is used in storage batteries (B-II). H$_2$SO$_4$ is anti-chlor (C-I), and PH$_3$ is applied in smoke screens (D-IV).
