Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Flu virus
Concept:

Viruses are classified structurally into naked (non-enveloped) and enveloped categories.

Solution:

  • The Flu virus (Influenza) is an enveloped virus.
  • When it buds from the host cell, its nucleocapsid (containing the genetic code) gets wrapped in a lipid bilayer membrane derived from the host.


Why other options are incorrect:

  • Hepatitis A, Enterovirus, Polio virus: These all belong to the Picornaviridae family and are strictly naked (non-enveloped) viruses. Their genetic code is only bound by a protein capsid.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
