Which of the following is a form of alternative dispute resolution?

Arbitration is a recognized form of alternative dispute resolution (ADR) that involves a neutral third party, known as the arbitrator, who is appointed to hear both sides of a dispute and make a binding decision. This method is often favored for its ability to provide a quicker, more cost-effective resolution compared to traditional court proceedings. Arbitration allows parties to maintain privacy, as the details of the resolution are not usually public records, and it often enables them to retain control over certain aspects of the process, such as the selection of the arbitrator.

The other options do not qualify as alternative dispute resolution methods. Voting typically pertains to decision-making processes in democratic contexts rather than resolving disputes. Consensus involves collaboration and agreement among parties, but it may not provide the decisive, enforceable outcome that arbitration does. Protesting is an action taken to express discontent or demand change regarding an issue but does not offer a structured approach to resolving conflicts between parties. In contrast, arbitration is a formalized process designed specifically for dispute resolution.
