Which statement describes the right to withdraw from a research study?

• A. Participants can join a study without consent.
• B. Participants must complete the study.
• C. The participant can withdraw from a study at any time.
• D. The participant can withdraw only with physician approval.

Answer: (C)

Autonomy and voluntary participation are central in research ethics. The statement that a participant can withdraw from a study at any time illustrates this right: a person may stop participating for any reason and without penalty. Researchers must honor the withdrawal, discontinue involvement for that individual, and handle any already collected data according to protocol. No physician approval is needed to withdraw, and insisting on continued participation would violate informed consent and the participant’s control over their involvement. The other options conflict with the principle of voluntary participation and the standard consent process.
