The principle states that the sale of liquor is illegal, and agreements relating to prohibited items do not exist in the eyes of the law. A and B entered into an agreement for the sale of liquor, and A failed to supply the agreed quantity. Let's test each option against this principle.
Because the agreement was for the sale of liquor, a prohibited item the principle treats as legally non existent, B cannot bring any legal action against A for failing to supply it.
Therefore, the correct answer is B cannot bring any legal action against A.
The principle's necessary condition is that the subject matter be a prohibited item, and once that condition is met, the consequence is that the agreement does not exist in the eyes of the law at all. We can test each option by checking whether this condition and consequence apply to an agreement for the sale of liquor.
Since the agreement concerns liquor, a prohibited item, the principle's non-existence consequence applies, leaving B with no legal action against A.
Therefore, the correct answer is B cannot bring any legal action against A.
