Which of the following statements is true about prices charged by reputable vendors?

• A. they normally charge higher prices than less reputable vendors
• B. they always offer the lowest prices
• C. they charge more for some products but less for others
• D. their prices are unpredictable

Answer: (D)

Prices from reputable vendors aren’t fixed and can change based on a mix of factors like market conditions, demand, promotions, bulk discounts, and changes in supplier costs. Some items may be priced higher because they’re specialized or in high demand, while others may be discounted to move volume. This variability means you can’t reliably predict exact pricing across items or over time, which is why the statement that their prices are unpredictable is the best fit. The other options imply a uniform pattern (always lowest, always higher, or always the same relative to others), which isn’t typically true in real purchasing scenarios.
