Correct answer: B. Naked virus
- A. Icosahedral virus
- B. Naked virus
- C. Enveloped virus
- D. Bilayer virus
Explanation
Naked virus (non-enveloped): Lacks a lipid envelope; only has a protein capsid around its genetic material. This is the term for viruses without an envelope.Icosahedral virus: Refers to capsid shape (20-sided), not envelope presence.Enveloped virus: Has a lipid envelope derived from the host membrane.Bilayer virus: Not a standard term; viral envelopes are lipid bilayers.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
