Final Answer : A, Explanation :  Based on the boxplots, Vineyard B has the highest median case price at around $150, indicating that their wines are generally more expensive than those produced by Vineyards A and C. Vineyard A does have an outlier at around $145, but that is just one data point and does not necessarily reflect the overall trend of their case prices. The size of the IQR (Interquartile Range) for Vineyard C does not indicate which vineyard produces the most expensive wine. The smallest case price belongs to Vineyard A, but that does not necessarily mean they produce the least expensive wine overall. Therefore, Vineyard B is the best choice as the producer of the most expensive wine in this scenario.
