Choice B rationale

Fomites are inanimate objects that can carry and transmit pathogens, such as a glass, door handles, or medical instruments.

Choice C rationale

Prions are infectious proteins that cause neurodegenerative diseases, not inanimate objects that transmit infection.

Choice D rationale

Interferons are proteins produced by cells in response to viral infections and do not relate to the transmission of pathogens via inanimate objects. .
