Which of the following is a type of alternative dispute resolution (ADR)?

Arbitration is considered a type of alternative dispute resolution (ADR) because it involves resolving disputes outside of traditional court settings. In arbitration, parties agree to submit their dispute to one or more arbitrators who make a binding decision on the matter, thus providing a resolution without the need for a court trial. This process is typically more flexible, faster, and can be less costly than litigation.

In contrast, court trials and litigation refer to formal processes carried out in the courtroom, where a judge (and sometimes a jury) decides the outcome based on legal arguments and evidence presented. An injunction, on the other hand, is a court order that requires a party to do, or refrain from doing, a specific act and does not represent a form of dispute resolution but rather a legal remedy or preventive measure. Therefore, arbitration stands out as a recognized method within ADR, aimed at facilitating resolutions in a more amicable and efficient manner.
