    Solution:

    The given statement is true.
    Concept- The term "rust" refers to the reddish-brown iron oxide that forms on everything composed of iron. When oxygen in water reacts with iron, iron oxide is created.
    Iron (III) hydroxide and hydrated iron(III) oxide make up the rust.
    Iron and water in the atmosphere undergo a redox reaction, which causes iron to rust.
     Now, the issue is whether rusting requires both air and moisture.
     In fact, this is true. For iron to rust, both air and moisture are required.
    The oxidising agent that works best is oxygen. Iron reacts with oxygen in the air to change its state of oxidation. Iron undergoes reduction, or the loss of electrons. The response can be expressed as:
    Iron cannot be directly combined with oxygen. It uses moisture-containing water as a catalyst to quicken the process.
    Thus, for iron to rust, both air and moisture are necessary.
    Water and oxygen are derived from air and moisture, respectively.
    Hence, the given statement is true.
