Starr is an agent of a disclosed principal, maple. on may 1, starr entered into an agreement with king corp. on behalf of maple that exceeded starr's authority as maple's agent. on may 5, king learned of starr's lack of authority and immediately notified maple and starr that it was withdrawing from the may 1 agreement. on may 7, maple ratified the may 1 agreement in its entirety. if king refuses to honor the agreement and maple brings an action for breach of contract, maple will

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.
