Solution- -A- catalystFor iron to rust- three things are needed- iron- water and oxygen- When these three type of molecules are near each other- the water acts as a catalyst for the rust reaction- acting as a good electrolyte permitting easier electron flow between atoms-

Without water, iron will not rust at ordinary temperatures. Iron and oxygen may lie together for hundreds of years without any chemical reaction taking place. The moment a drop of water is added rusting can begin. Water acts as a:
catalyst
wettening agent
chain reactor
solvent

Solution:- (A) catalyst
For iron to rust, three things are needed: iron, water and oxygen. When these three type of molecules are near each other, the water acts as a catalyst for the rust reaction, acting as a good electrolyte permitting easier electron flow between atoms.
