Which of the following best describes "forensic science"?

The term "forensic science" is best defined as the application of scientific methods and principles to investigate crimes and analyze evidence. This field encompasses a variety of disciplines such as biology, chemistry, and physics, which are used to collect and evaluate physical evidence from crime scenes. Forensic scientists apply their expertise to interpret data, identify substances, and provide objective findings that can be presented in a court of law. This crucial role supports law enforcement agencies in solving crimes and ensuring that justice is served.

In contrast, the other options do not encapsulate the essence of forensic science. Scientific research on societal impacts of crime focuses on the broader implications of criminal behavior rather than evidence analysis. Law enforcement's administrative duties pertain to organizational tasks rather than the scientific examination of evidence. Lastly, the analysis of witness testimonies in trials relates specifically to the testimonial aspect of legal proceedings and does not involve scientific methodologies.
