Final answer:
The oral contract for the sale of George's office building is not enforceable.
Step-by-step explanation:
The subject of this question is Law and the grade level is High School.
In this situation, the oral contract for the sale of George's office building is not enforceable. Generally, contracts for the sale of real estate must be in writing to be enforceable. This requirement is known as the Statute of Frauds, which is a legal principle that requires certain contracts to be in writing to prevent fraud or misunderstandings.
Since the contract between George and Martha was an oral contract and not in writing, it would not be enforceable by either party.
