Explanation:

Tracking Signal:

The tracking signal indicates whether the forecast value is unbiased or not.
The forecasting model is used in almost every field, in case the model gives a very high or low value is an indication of forecasting error which is also known as biasing.
To check if the forecast value is biased or not we use the formula of tracking signal to track the predicted value is within range or not.
The range of tracking signal (T.S) varies from 3 to 8. In this case the value 9 does not fall in this range, hence 9 is the correct answer.
