Final answer:
The student's question is physical forensics (option c), which is essential in criminal cases because it provides concrete, scientific evidence that can be critically examined and verified beyond a reasonable doubt.
Step-by-step explanation:
Physical forensics. This field is often critical to the outcome of criminal cases because it relies on tangible, scientific evidence to support claims made in court.
Physical forensics includes various forms of evidence such as DNA, fingerprints, bloodstains, or ballistic analysis. In contrast to things like hearsay, which is generally inadmissible in court, physical forensic evidence can be directly examined and utilized to establish the facts of the case. The Sixth Amendment ensures that defendants have the right to confront and cross-examine witnesses, further underscoring the importance of reliable, concrete evidence in the form of physical forensics.
The use of eyewitness testimonies, although valuable, is known to be less reliable and requires support from physical evidence to strengthen the case beyond a reasonable doubt. In fields like criminal justice, the support of arguments through verifiable evidence is fundamental, and physical forensics serves as a critical tool in upholding the integrity of the judicial process.
