Answer: (B)

The main role of peer review in scientific research is to ensure the reliability and credibility of findings. During the peer review process, other experts in the field critically evaluate a researcher’s work before it is published. This includes assessing the methodology, data analysis, and conclusions drawn in the research. Peer reviewers look for potential biases, errors, and the overall validity of the study, which helps to uphold the integrity of scientific literature. Through this rigorous review process, only research that meets the high standards of the scientific community is published, which fosters trust in the results and enhances the overall quality of science. This function is crucial in maintaining a robust scientific dialogue and advancing knowledge effectively.
