Answer:
The contract wasn't formed because of closing of offer due to closing of offeree.
Step-by-step explanation:
The offeree can only accept the offer if:
1. The Offer is not closed.
2. The offerer is alive.
3. No offerer qualifies age limit.
4. The Offered is in senses which means he is not drunk or suffering from mental illness that affects thinking of what is right or wrong for him.
Clearly from the above conditions the condition 2 is not satisfied here because offerer died before the acceptance of offer. Hence the contract was not formed and Executor did right by refusing to deliver the deed to black-acre in exchange for money.
