Answer:
The answer is c) dismissed the suit because of the arbitration agreement
Explanation:
The court dismissed her suit becasue she signed a contract which had an arbitration clause which bound her that she should resolve any dispute through arbitration. If you sign an arbitration agreement you cannot sue your employer, but the agency can investigate, encourage you and your employer to settle, and even sue your employer on your behalf (although these lawsuits are exceedingly rare). It is legal for your employer to rescind a job offer if you refuse to sign an arbitration agreement.
