At a meeting with your fellow executives at KFC, you're discussing introducing a new low-fat grilled chicken nugget option, which is significantly different from the company's usual menu items. The CEO wants to get an accurate sales forecast for the product before giving it the green light. Of the following arguments in favor of using various techniques, which one makes the most sense to you?
a. Taylor recommends getting sales forecasts from store managers, a form of sales force composite, since they're so familiar with KFC customer preferences.
b. Alex suggests surveying potential buyers since the company has access to so many consumers.
c. Bruce points out that using data from other similar products to conduct a trend analysis would be the least expensive choice.
d. Anya claims that test marketing in a few select cities will provide the most realistic information on actual purchases.

Asking Store managers is baseless because we haven't offered any similar product in the past. So they don't have customer knowledge in this particular area. So option A is incorrect.

The reason is that surveying customers might result in good initial response and later the company see poor actual response due to fewer sales because customer usually try to express their opinion which not always right. So Option B is incorrect.

Furthermore, using data which is past data might result in the unrealistic assumptions because of rapidly changing environment. So this option C is also not a reliable option.

The Option D says going for test marketing in some cities will help in checking the customer actual response and also enables fast decision making. So the option D is the best option here because of the benefit of test marketing is that it doesn't considers opinions, trend analysis, etc. it considers actual response of customer.
