Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Lymphocytes
Concept: Lineage of antibody-secreting cells.

Solution: Plasma cells—which produce antibodies—are terminally differentiated forms of B-lymphocytes.

Why other options are incorrect:
  • Option B & Option C: Basophils and eosinophils are granulocytes that release inflammatory mediators.

  • Option D: Erythrocytes are non-nucleated cells that transport gases.

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.
