Answer:
e. cannibalization
Step-by-step explanation:
Based on the information provided within the question it can be said that this is most likely due to cannibalization. In business terms, this refers to a decline in sales due to the fact that the company introduces a new product with the hope of increasing sales, but instead that product takes the spotlight and causes the sales for other products that provide more profit to actually decline. Which is what the grilled chicken is doing to the burger products in this scenario, causing Fenton's overall sales revenue to decline.
