Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 270-280
Concept:

Gestation is the period of intrauterine fetal development from conception to birth.

Solution:

  • In humans, the standard gestation period is universally recognized to be roughly 9 months.


  • Calculated from the first day of the last menstrual period (LMP), this is approximately 40 weeks, or \(280 \text{ days}\).


  • Calculated directly from fertilization, it is about 38 weeks, or \(266 \text{ days}\). The range \(270-280 \text{ days}\) accurately represents this timeline.


Why other options are incorrect:

240-250 days is significantly premature. Over 300 days is extremely post-term and medically abnormal.
