Which of the following can give an enterprise dealing in instant coffee a competitive edge ?

Option D is the correct answer.

For an enterprise dealing in instant coffee, the factors that provide a competitive edge are:

1) Quality and taste: Customers are primarily drawn to products that meet their expectations in terms of taste and quality. This is a critical factor for a coffee business.

3) Ambience and customer relationship: While selling coffee, creating a positive customer experience and maintaining good relationships can improve customer retention and loyalty.

Population increase in the city (option B) is not a direct factor that provides a competitive edge, as it doesn’t guarantee increased preference for the business or its products.
