Step-by-step explanation:
The correct answer that most helps to reconcile the discrepancy indicated is d) External factors influenced the outcome.
This option suggests that factors outside of the scope of the research may have influenced the outcome, potentially explaining the discrepancy. By considering external factors, the researchers can assess if there were any variables that were not accounted for in the analysis.
For example, if the research was investigating the effect of a certain drug on a disease, external factors such as the patient's lifestyle, diet, or other medications they were taking could have influenced the outcome and resulted in the discrepancy.
