A selection of sizes a product is made in that caters for the majority of a market.

• A. Range of sizes
• B. Reach
• C. Ratio data scale
• D. Secondary data

Answer: (A)

Offering multiple size options to fit a broad user base is the idea behind this item. The best choice describes the set of different sizes a product is made in to cater to the majority of the market. By providing a range of sizes, designers can cover more body types and use cases, improving usability and fit while balancing production costs. The other terms don’t describe this idea: reach is about how far something extends or can be accessed, not about the product’s dimensions; ratio data scale is a statistical measurement concept dealing with true zero and meaningful intervals, not physical size options; secondary data refers to information gathered from existing sources, not the range of sizes offered.
