Answer:
Because in boiled water there is no oxygen and a thin oil layer separates the nails from atmospheric oxygen. Then nails in the test tube A do not get rust. -Nails in test tube B also do not get rust because soda-lime removes the rust if the nails contain rust. Then the nails in test tube B are safe.
