The correct answer is C. So employees won't be afraid to be honest
Explanation:
When gathering information from human subjects, it is important to guarantee confidentiality. This principle implies information gathered by the researcher can only be used for research purposes and this is not revealed to the public except by making subjects anonymous. This is important not only due to ethics but because it guarantees subjects feel free to provide information and be honest.
This idea applies in the case of Cory because making employees'responses anonymous they would feel free to speak or they would not be afraid to be honest, especially as in this case, employees might be afraid of possible consequences if they criticize their company, employer or work conditions.
