Rust and smut belong to the phylum
Correct answer: C. basidiomycota
- A. zygomycota
- B. ascomycota
- C. basidiomycota
- D. deuteromycota
Explanation
Rust and smut diseases are caused by fungi that belong to the phylum Basidiomycota. These fungi are known for producing complex fruiting bodies and are significant plant pathogens. The other options, Zygomycota and Ascomycota, include fungi that play different roles in the ecosystem, such as decomposing organic matter or forming mutualistic relationships. Deuteromycota, meanwhile, is an outdated classification for fungi with unknown sexual stages and does not specifically cater to rust and smut pathogens.
