Answer: (C)

The term "peer review" in scientific research refers specifically to the evaluation of scientific work by experts prior to publication. This process ensures that the research is rigorously assessed for its validity, significance, and originality by individuals who are knowledgeable in the same field. Peer review serves several essential functions: it helps maintain high standards in scholarly publishing, provides credence to the research being presented, and offers constructive feedback that can improve the work before it is made available to the broader scientific community.

Through this evaluation, potential issues such as methodological flaws, data misinterpretation, or theoretical errors can be addressed, enhancing the credibility and quality of published research. This critical step is a foundational aspect of the scientific process, as it enables other researchers to build upon validated findings with confidence.
