I think because other gases are inert. So, the correct answer is b.

This is not a fact @Aditee.

I think the correct answer is hydrogen.

K.Manvithasai said:   9 years ago
The correct option is A.

Parikshit said:   9 years ago
I do think so the correct option is A. It can't be B at all. Just pay attention that iron gets rust due to moisture mostly from oxygen.

SHYAM said:   9 years ago
The correct option is B. I also agree.

Please someone clearly explain the mechanism behind this process, it's very confusing for me.

Dhruv Gaur said:   9 years ago
The correct option is b. I agree.

I think its option (A) as the content of hydrogen sulphide in the air is almost 0.

I think that option oxygen. As brass gets react with oxygen and get rust.
