Which of the following third parties utilized in alternative dispute resolution proceedings has the authority to make a binding decision?

Correct Answer: Option C — Arbitrator

An arbitrator is the only third party in this list with the authority to render a binding decision. Mediators and facilitators assist in reaching a voluntary agreement, while fact-finders only provide reports. Arbitration is specifically designed to resolve deadlocked disputes through a definitive, enforceable ruling by an impartial party.
