The National Research Act of 1974 established which of the following?

The National Research Act of 1974 was pivotal in shaping the ethical framework surrounding human subjects research in the United States. This legislation specifically established the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. The Commission was tasked with identifying ethical principles and guidelines essential for conducting research involving human subjects.

The formation of this Commission marked a significant step toward ensuring that ethical considerations are duly addressed in research practices. Its work ultimately led to the creation of crucial documents, such as the Belmont Report, which outlines key ethical principles, including respect for persons, beneficence, and justice. Thus, establishing the National Commission was foundational for developing standards and regulations that would protect human subjects in research, making this option the most accurate reflection of the Act's impact.
