(1) By a person designated in the terms of the trust to act as successor trustee;

(2) By a person selected by the charitable organizations expressly designated to receive distributions under the terms of the trust instrument if the Attorney General of West Virginia either concurs in writing to the selection or fails to make a written objection to the selection within ninety days after receiving by certified or registered mail a notice of the selection by the charitable organizations; or

(3) By a person appointed by the court having jurisdiction over the trust.
