so umm which one and why?

The iron nail will rust, but the aluminum and the galvanized iron nail will not. The iron nail will rust according to 4Fe + 3O2 ===> 2Fe2O3. The aluminum nail will form a protective coating of Al2O3 around it, which will prevent further corrosion. The galvanized iron nail has a coating of molten zinc over it, which will prevent it from rusting for the same reason.

Generally, iron rusts when exposed to air and water. The iron nail will definitely rust.
Galvanized nails will not because they are iron nails plated with zinc, and thus the iron is not exposed to the atmosphere and thus will not rust.
Although aluminium is a reactive metal (meaning more likely to react with air and water to "rust"), aluminium reacts with oxygen to form an inert, non-porous layer of aluminium oxide on the surface. Thus aluminium is not exposed to the atmosphere and will not rust.
By the way, "rust" is a term that can only be used for
iron. For other metals a better term will be "corrode". Cheers! =)

The iron one will rust. Rust is defined as oxidized iron. Aluminum does not rust but it will oxidize. The galvanized nails wil not rust at all.

Perhaps very slowly. Remember, rusting is basically a slow form of burning, the metal oxidizes. If there is oxygen dissolved in the water then it could rust, but if there isn't any oxygen there then it would remain as it is. It would also rust much faster if merely dampened and then put in open air, or better yet dampened with salt water.

Iron and Aluminium would both rust but Iron would rust faster. Galvanised nails would not rust. These answers depend on the conditions: 298K, 1atm and 1M concentration.
