Solution:
Concept: Corrosion is the gradual deterioration of metal caused by the attack of air, water, moisture, and environmental chemicals. Rusting is the corrosion of iron particles. Rusting is the process of iron forming a reddish-brown deposit on itself as a result of water, air, and oxygen present in the environment.Rust is an iron oxide coating that forms on iron objects chemically. Rust causes iron objects to become toxic and lose their aesthetic appeal. Iron, water, and oxygen are required for the creation of rust. Despite being a complicated procedure, the chemical formula is just,
Iron is painted to avoid rusting so that the iron layer cannot come into touch with the environment and react with oxygen to generate iron oxide, preventing the development of rust.Oiling the iron items is another approach to stop it from happening so that air and water don't come into touch with each other. Linseed oil aids in rust removal from iron objects. Any acrylic paint works to keep iron from rusting.
Hence, the correct option is option 1.
