Obstructing law enforcement's ability to perform duties?

• A. Interference with Investigation
• B. Murder Prosecution
• C. Plain Clothes Officers
• D. First Amendment Rights

Answer: (A)

The main idea here is actions that stop or slow police from doing their job—especially during investigations. Interference with Investigation is the term that directly describes hindering an investigation by law enforcement, such as obstructing interviews, delaying a scene, or giving false information. That makes it the best fit for obstructing law enforcement’s ability to perform duties.

The other options don't capture this idea. Murder Prosecution refers to pursuing charges for homicide, not to hindering police work. Plain Clothes Officers describes a type of officer, not an action that obstructs duties. First Amendment Rights protect freedoms like speech and assembly, which is unrelated to obstructing law enforcement.
