Which of the following statements about informed consent is correct?

Informed consent is fundamentally essential in research involving human subjects, as it ensures that participants are fully aware of their involvement in a study, the risks, benefits, and their right to withdraw at any time. Obtaining informed consent prior to any research activity is a key element in upholding ethical standards and protecting participants' autonomy. This process provides individuals with the opportunity to make informed decisions about their participation based on a clear understanding of the research.

The principle of informed consent underscores the ethical obligation researchers have to ensure that participants are not only invited to take part in a study but also fully comprehend the implications of their participation. Thus, it serves not merely as a procedural requirement but as a safeguard for the rights and welfare of research participants.
