Which term describes the procedure by which a subject voluntarily agrees to participate in a clinical trial after understanding all information?

• A. Assent
• B. Confidentiality
• C. Informed consent
• D. Randomization

Answer: (C)

Informed consent is the process where a person is given clear, thorough information about a clinical trial—the purpose, procedures, potential risks and benefits, and alternatives—and is allowed time to understand it before voluntarily agreeing to participate, usually by signing a consent form. This ensures the participant’s autonomy and allows a voluntary decision without coercion. Assent relates to agreeing from someone who cannot legally consent (like a minor) and is not the full formal consent process; confidentiality is about protecting personal information; randomization describes assignment to study groups, not the consent process.
