Answer:A- when market share for a product has dropped for three consecutive quarters
Explanation:
Market Research is the gathering of valuable information and data about a particular product or service. This is a very important part of business as the marketing research will help the company get detailed information about their products, how acceptable the product has been in the market, the complaints consumers have on the product and how the products can be improved.
Marketing research provides data that organisations need to stay and remain in business.
