Answer: (B)

Peer review plays a crucial role in the scientific process by ensuring that studies undergo a thorough evaluation by experts in the field before publication. This process helps to maintain the integrity of scientific literature, as it assesses the validity, reliability, and accuracy of research findings. During peer review, reviewers scrutinize the methodology, data analysis, and conclusions drawn by the authors, identifying any potential errors or biases.

This critical evaluation helps guarantee that only research that meets established scientific standards is published, thereby enhancing the overall credibility of the scientific community. The peer review process also encourages transparency, as authors may need to revise their studies based on feedback, ultimately strengthening the research. By fostering rigorous scrutiny, peer review contributes significantly to the advancement of knowledge and the trustworthiness of scientific studies.
