The Following Are Advantages of Using Surveys of Buying Intentions

The following are advantages of using surveys of buying intentions except:

A) research gives the forecaster a viable forecasting basis when others may be inadequate or impossible to use, such as when there is no historical data
B) buyer intentions can be inaccurate, since what people say they're going to buy and what they actually buy can differ
C) forecasts are relatively fast and inexpensive when only a small number of customers are surveyed
D) research gives the sales forecaster a good prediction of customers' buying intentions and some of the subjective reasoning behind their answers
