Answer 2

Option B Sulphur Dioxide is the right answer.

• Steel is an alloy of iron and carbon.
• Sulfur dioxide is a toxic gas with the smell of burnt matches.
• In the absence of water, sulfur dioxide is not at all harmful to steel.
• But in the presence of moisture, sulfur dioxide reacts with water to produce corrosive and acidic sulphuric acid.
• This sulphuric acid reacts with steel and causes damage to the steel.
• Acidic corrosives can cause accelerated corrosion of steel.
