Answer:
a. The agreement will be discharged due to true impossibility.
Explanation:
Since in the question, it is given that Baldrick was hired for three nights per week for an entire year. Due to food poisoning, he dies after nine months of agreement.
So, it is a contract in which two parties are involved which bound them to perform their dues and responsibilities.
Since he died so automatically the contract lapse because of true reasons or impossibility as it is impossible to fulfill the contract.
Hence, option A is correct.
