Explanation:

Maps and models use scales to represent real - world distances or sizes. A common way is verbally (e.g., "One centimeter represents one kilometer"), graphically (a marked line on a map), and as a ratio (where one unit is described in terms of another). Option A correctly lists these three common ways.

A. A scale can be described verbally, in words such as "One centimeter represents one kilometer", graphically, such as a marked miniruler on a map, or as a ratio, where one unit is described in terms of the other.
