Albugo candida produces

Answer: Option D

Albugo candida produces Oospores.
Albugo candida, commonly known as white rust, is a species of oomycete in the family Albuginaceae. A. candida is an obligate plant pathogen that infects Brassicaceae species and causes the disease known as white rust or white blister rust.
Thick-walled sexual spores, called oospores are produced which germinate, producing either vesicle inside the plant tissue, exit tubes with vesicles at the tip, or germ tubes. Further zoospores develop inside the vesicles. The infection is spread by either oospore-infected seed or by mechanical movement of sporangia.
