Solution : The correct option is to increase.
When iron rusts, its weight increases because iron oxide, which contains both iron and oxygen atoms, is formed. Rust is a hydrated iron oxide, also known as Fe 2 O 3 .xH 2 O. The iron atoms join with oxygen atoms to produce the iron oxide complex, and because of this, the iron's total weight increases as it rusts.
