CITI Training Practice Exam

Assent is defined as the agreement of someone who cannot legally consent for themselves, such as a minor or person with a cognitive impairment. This is different from legal consent, which is obtained from a guardian or sponsor. Option A is incorrect because the trial sponsor is responsible for organizing and funding the trial, not for providing assent. Option B is incorrect because it implies that legal consent and assent are interchangeable terms, when in fact they are distinct concepts. Option D is incorrect because it refers to refusal, which is the opposite of assent. Therefore, only option C correctly defines assent in clinical trials.
