Choice A rationale:

Ingestion of contaminated water is the primary mode of transmission for certain gastrointestinal infections, such as viral gastroenteritis, but it is not the main route for viral meningitis transmission.

Choice B rationale:

Mosquito or tick bites are associated with the transmission of various vector-borne diseases, such as West Nile virus, Lyme disease, and others. However, they are not the primary mode of transmission for viral meningitis.

Choice C rationale:

Direct contact with respiratory droplets or saliva from an infected person is the most common mode of transmission for viral meningitis. Viruses causing meningitis, such as enteroviruses, are often present in respiratory secretions and saliva.

Choice D rationale:

Inhalation of fungal spores is related to the transmission of certain fungal infections, such as aspergillosis or histoplasmosis, but it is not the primary mode of transmission for viral meningitis.

Choice E rationale:

Contact with contaminated soil is not a typical mode of transmission for viral meningitis. It might be relevant for some soil-transmitted infections but not for viral meningitis.
