Which term refers to the use of techniques to solve crimes?

• A. Investigative Work
• B. Fingerprint Classification Systems
• C. Health and Nutrition Status
• D. Comma

Answer: (A)

Solving crimes involves gathering evidence, following leads, interviewing witnesses, and analyzing forensics to reconstruct events. This coordinated process is investigative work. Fingerprint classification systems are specific tools used within investigations, but they don’t name the overall process. Health and nutrition status has no direct relation to crime-solving, and a comma is punctuation, not a method for solving crimes.
