Answer:
The correct answer is C: likely that a court will allow the rescission based on a mistake of fact.
Step-by-step explanation:
Brian was not aware of that fact that the horse is incapable of breeding at the point he buys it, but Larson assures Brian the horse is healthy. In this light, if Brian sues to cancel the contract with Larson, the court will allow it based on a mistake of fact. This way the court will reduce any civil liability or criminal culpability because Larson might not know that the horse cannot breed, although he is certain that the horse is healthy.
