All of the following viruses are enveloped EXCEPT:

  • A. Hepatitis C virus
  • B. Hepatitis B virus
  • C. Hepatitis A virus
  • D. Hepatitis D virus
Correct Answer: C

Rationale: The correct answer is C: Hepatitis A virus. This is because Hepatitis A virus is a non-enveloped virus, while choices A, B, and D are all enveloped viruses. Enveloped viruses have a lipid bilayer membrane surrounding their protein capsid, aiding in their ability to infect host cells. Hepatitis C, B, and D viruses all possess this lipid envelope, making them enveloped viruses. Hepatitis A virus, on the other hand, lacks this lipid envelope and is classified as a non-enveloped virus. Therefore, the correct answer is C.
