Final answer:
The inappropriate way to use name signs, which are part of American Sign Language, is when a person is right in front of you. It is considered rude to refer to someone with their name sign instead of addressing them directly when you are having a direct communication with them.
Step-by-step explanation:
The question asks about the inappropriate use of name signs in communication. In this context, name signs refer to the personal signs used within the Deaf community to identify individuals once they have been formally introduced. These are a part of American Sign Language (ASL) and serve as a personal identifier similar to a spoken name. An inappropriate way to use name signs is option A) When a person is right in front of you. In direct communication, it s generally considered rude to refer to someone using their name sign instead of addressing them directly. The other options (B, C, and D) are appropriate uses of name signs. They are used to refer to a person not present, to get someone's attention, and after introductions, adding the name sign after fingerspelling a person's name every time.
