Which option best represents the practice that protects a participant's right to withdraw from a study or their data?

• A. Informed consent
• B. Anonymity
• C. Right to withdraw
• D. Debriefing

Answer: (C)

Respect for autonomy in research is what this item focuses on. The right to withdraw guarantees that participants can stop taking part at any time and, where possible, have their data excluded from analyses. This directly protects their ongoing control over participation and what happens to their information, reinforcing that participation is voluntary rather than coercive. While informed consent covers agreeing to participate with full knowledge, anonymity protects identity, and debriefing provides post-study information, none of those alone ensures ongoing withdrawal rights. The right to withdraw is the specific mechanism that preserves a participant’s ability to change their mind and manage their data even after the study has begun. If data has already been collected and anonymized or used in analyses, withdrawal might not undo those existing data, but participants should still be able to stop further data collection and request removal where feasible.
