Answer:
The correct answer is letter "A": High end and low end.
Explanation:
Disrupting businesses are those whose creation represents the replacement of a product or service in the market. Streaming movie services such as Netflix, for instance, lead Blockbuster to bankruptcy. High-end disruption occurs when the innovation fulfills a need that companies in the market were not able to fulfill. Low-end disruption occurs when the innovation that is introduced by a company is greater than the rate at which consumers can adopt the new product.
