Final answer:
The principle that ensures an individual's responses or results cannot be linked to their identity is B) Anonymity. Anonymity protects a participant's privacy and ensures that sensitive personal information remains confidential during a study.
Step-by-step explanation:
The principle that ensures an "individual's responses or results cannot be linked to his/her identity" is B) Anonymity. Anonymity is a critical aspect of research ethics, ensuring that participants’ privacy is protected and their personal information is not disclosed. This concept is especially important when dealing with sensitive topics or information that could potentially harm the participant if leaked. For example, researchers studying topics that might require participants to disclose personal or sensitive information will often use anonymity to assure participants that their responses cannot be traced back to them personally. The importance of anonymity is underscored in situations where informed consent is involved, and when the nature of the research means participants might skew their responses if they felt their identity could be revealed.
The principle that ensures that an individual's responses or results cannot be linked to their identity is Anonymity. Anonymity refers to the condition of being unknown or unidentified. When participants can respond to questions anonymously, they are more likely to share honest answers without the fear of their identity being revealed.
