Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Carbon
Concept:

Bio-elements combine to form the living mass of an organism. While Oxygen is the most abundant element overall (65%), it is not listed in the options.

Solution:

  • We must select the most abundant element from the given choices based on standard human body composition percentages:


  • Carbon: 18%


  • Nitrogen: 3%


  • Sulphur: 0.25%


  • Manganese: Trace element


  • Therefore, Carbon is the most abundant element among the provided options.


Why other options are incorrect:

  • Nitrogen, Sulphur, and Manganese make up significantly smaller percentages of human body mass compared to Carbon.
