To determine which of the given options allows shoppers to make accurate comparisons between item sizes and brands, let's analyze each option carefully:

1. Per Unit Cost: This refers to the price of a product per standardized unit (like per ounce, per liter, etc.). It allows consumers to compare items of different sizes and brands based on how much they are getting for their money.

2. Expiration Date: This indicates how long the product is safe to use but does not aid in comparison between sizes or brands.

3. Sale Price: While this shows the discounted price of a product, it does not necessarily help in comparing items of different sizes or brands directly.

4. Bulk Cost: This refers to the total price when purchasing in bulk, which can sometimes be misleading as it might not reflect the per-unit cost accurately to compare smaller sizes or different brands.

Conclusion:

Among these options, Per Unit Cost is the best choice because it provides a standardized method for comparison based on size and price, thereby allowing for accurate comparisons between different items and brands.
