Action for declaratory relief: A person who is injured or is in danger of suffering damages can ask for a declaratory judgement on the “unfairness” of the act. The unfairness of competition and existence of damages - if any - are to be proved by the claimant under the general rules of tort and law of civil litigation procedure. The purpose of the action is generally to ascertain a legal ground for a future action for damages, indirectly to prevent damage from acts of unfair competition or to stop the running of the statue of limitations. Therefore, the correct option is A.
