Question:
Which gas is primarily responsible for the corrosion of metals and monuments in polluted urban environments?
Which gas is primarily responsible for the corrosion of metals and monuments in polluted urban environments?
Show Hint
Acid rain is mainly caused by
\[
\boxed{\mathrm{SO_2}\ \text{and}\ \mathrm{NO_x}}
\]
leading to corrosion of metals and damage to monuments.

- Sulphur dioxide
- Carbon monoxide
- Methane
- Nitrogen
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Sulphur dioxide (\(\mathrm{SO_2}\)) reacts with atmospheric moisture to form sulphurous and sulphuric acids.
These acids cause acid rain, which corrodes metals and deteriorates monuments made of marble and limestone.
Hence,
\[
\boxed{\text{Sulphur dioxide}}
\]
is the correct answer.
Therefore,
\[
\boxed{(A)}
\]
