Answer:
The correct option is Cannibalization
Step-by-step explanation:
Cannibalization is the reduction in sales of an existing brand due to introduction of a new brand which could occur because both products share the same customer base or that they are competing brands due to the need they serve.
This implies that the new product is winning the hearts of the older product's customers rather than capture a new set of consumers,hence it could be said that the strategy of new product introduction has failed to yield the desired results since market share overall is not growing.
