Someone who contends with, opposes, or acts against your interest.

Someone who contends with, opposes, or acts against your interest.

• A. Informant
• B. Anonymous informant
• C. Confidential informant
• D. Adversary

Answer: (D)

The main concept is recognizing a person whose aims conflict with yours in an investigation. An adversary is someone who contends with, opposes, or acts against your interests, making them an opponent or rival in the case. This is different from an informant, who provides information to help the investigation, whether anonymously or under a confidential arrangement. Those roles describe cooperation, not opposition. So the term that best fits someone who contends with or acts against your interest is adversary.
