Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Antibodies, antigen
Concept:

The humoral immune response is a direct reaction to foreign molecular markers.

Formula:

None

Solution:

  • When White Blood Cells (specifically B-lymphocytes) detect a foreign shape (an antigen), they differentiate into plasma cells.


  • These plasma cells synthesize and release highly specific antibodies (immunoglobulins).


  • These antibodies bind to the antigens to neutralize them, thus providing immunity.


Why other options are incorrect:

  • WBCs do not produce antibiotics (fungi and bacteria produce antibiotics).


  • Antibodies are not produced in response to healthy RBCs (unless it is a mismatched blood transfusion).

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.
