Which criminal justice professional is responsible for collecting evidence from a crime scene? a.) police officer b.) private detective c.) forensic scientist d.) paralegal

C) Forensic Scientist.
Technically, the correct term would be a crime scene investigator (CSI), but this answer seems to be the closest to that. Police are enforcers, private detectives are essentially freelance and cover all bases of tracking a crime, and a paralegal is essentially a lawyer's apprentice. 

I’d say either a or d i’m sorry if it’s incorrect.
