Answer:
The answer is: D. not made an offer because under the circumstances a reasonable person would not conclude that John had intent to make an offer.
Step-by-step explanation:
This is because of the circumstances leading to making the offer. One of the things that makes an agreement or contract null is how the decision was made. Through undue influence or duress.
A reasonable person will not consider John's pronouncement as an offer because it was an offer influenced by the turn of events. The horse, Prince Charming came in last and John said it because he was embarrassed and frustrated. If his horse came in a better position, there is a possibility that he won't put it up for sale.
Only if he repeats the offer in a saner and calmer state of mind should it be considered else, it should not be seen as he had an intent to offer.
