Solution
The correct option is A Loose smut of wheat
Loose smut, caused by the fungus Ustilago tritici. Loose smut is internally seed-borne. Loose smut replaces grain heads with masses of spores which infect the open flowers of healthy plants and grow into the seed, without showing any symptoms. The loose smut fungus is carried as dormant mycelium within the healthy-appearing seed and is spread by planting the infected seed.
Covered smut of barley is externally seed-borne, spread by spores from diseased plant heads to the surface of healthy seeds.
Corn stunt and the soft rot of potato disease are bacterial diseases.
