Correct options are A) , B) and C)


Iron articles are often painted, hence for rusting to occur the open iron surface needs to be exposed to atmosphere. 

Moisture contains water and it is an important component in the reaction to form rust from iron.  

Air contains oxygen which is majorly the reason for the formation of iron oxide or rust. 
 4Fe+ 3O2 + 6H2O --------> 4Fe(OH)is the reaction that represents rust formation. 


Hence, the option(A), (B) and (C) are the correct answers.
