Final answer:
Viruses can spread via direct contact, exposure to contaminated body fluids, and inhalation of airborne particles; hence, all provided options are correct.
Step-by-step explanation:
Viruses may spread through a number of routes, including direct contact such as skin-to-skin contact, touching the same surfaces, and through oral transmission from sharing items like drinking glasses. Additionally, they can also spread by airborne transmission, where someone inhales virus-laden droplets expelled by an infected person via coughing or sneezing. Infections can also occur through contact with contaminated body fluids, such as blood, semen, and saliva, in cases like IV drug use, sexual transmission, and healthcare workers treating infected patients. Therefore, the answer to the question is (D) All the answers are correct, indicating that viruses can spread through direct contact, exposure to contaminated body fluids, and inhalation of airborne particles.
