Answer:
The correct answer is letter "B": Secondary meaning.
Step-by-step explanation:
Toys "R" U.S., Inc. sued Canarsie Kiddie Shop, Inc. in the late 1970s since Kiddie started to promote its children clothing as Kids "R" U.S. By that time, Toys "R" was a major children clothing store with a vast number of branches all over the U.S. The same company stated that the use of Kids "R" by Canarsie created confusion among consumers adopting the secondary meaning trademark law that implies Toys "R" products was so spread that the similarity with Kids "R" was related to Toys "R" somehow because the product offered was almost the same.
