Answer:
The correct option is D: Trimon may enforce this contract even if Clar Corporation does not wish to be bound.
Explanation:
As long as Ames had no actual, implied, or express authority, it is impossible for Trimon to enforce the contract. Furthermore, under agency law, it is required that the contract is either ratified completely, or its not ratified at all, and hence option A is correct. It is also possible for Trimon to withdraw from the contract because Ames has no authority unless Clar ratisfies the contract entirely, hence B is a correct statement. Also Clar can ratify the contract by actions, without having to state it, making C a correct statement also. The only incorrect statement is D.
