Quizplus · Accepted Answer

A flow variable is a variable that is measured over a period of time, typically as a rate or quantity per unit time. Options A, B, C and D are all examples of flow variables as they measure the amount or quantity of something over a given time period. Option E, however, is a stock variable as it measures the amount of money Susan has at a single point in time, rather than a flow over time.
