Who uses laboratory techniques to analyze evidence?

• A. Pharmacists
• B. Forensic Scientists
• C. Biotechnologists
• D. Teachers

Answer: (B)

The question focuses on who routinely uses laboratory techniques to analyze evidence from crime scenes. Forensic scientists specialize in applying chemical, biological, and physical analysis methods to evidence such as DNA, toxins, fingerprints, fibers, and ballistics. They work in crime laboratories (and sometimes at scenes) using tools like DNA sequencing, PCR, chromatography, mass spectrometry, and microscopy to identify substances, connect a suspect to an item, or reconstruct events. This focus on turning physical traces into information that supports investigations and the legal process makes them the most appropriate choice. Pharmacists mainly prepare and dispense medications; biotechnologists work with biological systems and products; teachers educate students.
