Answer:
Inert set
Step-by-step explanation:
"Nathan goes to a store to purchase laundry detergents. When Nathan looks around to make a brand selection, he realizes that he loves the brands Deit and Dolen, hates the brands Duss and Tone Out, and does not have much of an opinion about the brand Little Alls. In this scenario, Little Alls is clearly in Nathan's inert set.
An inert set are those brands or product that a customer is indifferent about even though he/she is aware of them but he/she is yet to try them out.
