The history of ethical regulations in human subjects research began with the: a. declaration of helsinkib. nuremburg codec. common ruled. belmont report

D. Belmont Report

Explanation:

If we have anything to emphasize in the history of bioethics, this is the report of Belmont (1978). He was born after the National Commission for the Protection of Human Biomedical and Behavioral Research in the United States after destroying a well-known Tuskegee experiment (on non-African American treated syphilis). This text includes the principles or criteria that guide research into people in biomedicine. Today, the Belmont Report is still considered a reference text for researchers.

The Belmont Report is the Intellectual Basis for a Common Rule, a set of regulations governing the research of human subjects that IRBs are tasked with implementing.
