Solution(By Examveda Team)

Rust includes in Basidiomycotina.
The Basidiomycota also contains perhaps the most important plant pathogens, the rusts and the smuts. These fungi do not produce macroscopic fruiting bodies, but instead bear their spores on the stems, leaves, and flowers of host plants.
Rust fungi are highly specialized plant pathogens with several unique features. Rust fungi are obligate plant pathogens that only infect living plants. Infections begin when a spore lands on the plant surface, germinates and invades its host.
