Final answer:
The court can order Papa to deliver the second airplane as agreed.
Step-by-step explanation:
If the court orders specific performance in a breach of contract case, it means that the party who failed to fulfill their obligations must execute the contract as agreed upon. In this case, if Papa fails to deliver the second airplane, the court can order him to do so. This is a remedy often used when the subject of the contract is unique or of special value.
Option B, Papa must deliver the second airplane as agreed in the contract, is the correct answer.
