Answer:
C. Both of "A" and "B" above are correct.
Step-by-step explanation:
A sales forecast is an estimation of future revenue to be generated from sales that can be obtained by studying past data and trends, and analysing the market. A prediction of what sales will look like within a specified period of time in future, is then made.
In sales forecasting, anticipated events that may affect sales as well as predicted future sales trend in the coming year, are taken into consideration and are reflected in the sales forecast for the coming year.
