If these are the missing choices:
a. Lose since the May 1 agreement is void due to Starr's lack of authority.
b. Prevail since Maple's capacity as a principal was known to Starr.
c. Prevail since the agreement of May 1 was ratified in its entirety.
d. Lose since King notified Starr and Maple of its withdrawal prior to Maple's ratification.
My answer is D.
Maple will lose since King notified Starr and Maple of its withdrawal prior to Maple's ratification.
King, the third party, may withdraw from a transaction or agreement entered into with an agent, Starr, who exceeded her authority at any time prior to the principal's, Maple, ratification of the agent's unauthorized acts.
In the above scenario, King notified Maple on May 5 of King's withdrawal from the agreement on May 1, six days before Maple's attempted ratification on May 7. Thus, Maple's action will fail.
