Answer:
The correct answer is letter "D": set aside any award.
Explanation:
Arbitrators are individuals without the range of judges that are called in disputes to resolve a matter before taking it to court. Similar to trials, each party involved in the dispute present their defense in front of the arbitrator who promotes the mutual agreement between the two parties but, if that does not happen, the arbitrator provides a resolution that tends to be definite.
Arbitrators must be impartial. Thus, if the arbitrator meets with one of the parties and, eventually, the decision of that case favors that party, the court can take away any reward provided until an investigation is conducted.
