Samples from a skin disease in rabbits at a rescue centre contain thread-like hyphae. Staff start disinfecting the grooming brushes after each rabbit is groomed.
Which statement explains how this reduces the spread of the disease?
it kills fungal spores on the brushes so they are not transferred to another rabbit's skin
it kills bacteria on the brushes so they cannot release toxins into another rabbit's skin
it destroys virus particles on the brushes so they cannot enter another rabbit's skin cells
it kills fungal spores in the air so other rabbits do not breathe them in
