Naked viruses are

  • A.Enveloped
  • B.Nonenveloped 
  • C.Viruses that are genetically deficient and so incapable of producing infectious daughter virions
  • D.Infective agents free of protein, with low molecular weight RNA

Answer: B

Correct answer: Nonenveloped

A naked virus is simply one with no envelope - the capsid is its outermost layer. Such viruses are the tougher: having no lipid, they survive drying, detergents and the acid and bile of the gut, which is why so many of them spread by the faecal-oral route.
