Which of the following statements is true about the ListPrice thresholds mapping to 'low', 'medium', and 'high' PricingGroup?

• A. All of the above
• B. ListPrice <= 50 maps to low
• C. ListPrice > 50 and ListPrice <= 1000 maps to medium
• D. ListPrice > 1000 maps to high

Answer: (A)

This question tests how numeric thresholds divide a value into discrete PricingGroups. ListPrice is categorized as low when it's 50 or less (ListPrice <= 50). The next range uses ListPrice > 50 and ListPrice <= 1000 to map to medium, so values strictly greater than 50 up to 1000 fall into medium. Finally, ListPrice > 1000 maps to high. Together, these three conditions cover every possible ListPrice value without overlap: ≤50 is low, 50<value≤1000 is medium, and value>1000 is high. Since each individual mapping is true, the statement that all of them are true is correct.
