TDD is the acronym for:

• A. Telephone Device for the Deaf
• B. Telecommunication Devices for the Deaf
• C. Telecommunications Dealing with the Deaf
• D. Telecommunications Device for the Hearing Impaired

Answer: (B)

Understanding what TDD stands for in telecommunications is the idea this question tests. TDD refers to devices that Deaf users use to communicate over telephone networks. The best fit is Telecommunication Devices for the Deaf because it directly describes the equipment designed for Deaf users to facilitate communication. The other phrasings don’t match the intended meaning: one would suggest a single device and would alter the acronym; another option talks about dealing with the Deaf and isn’t a device at all; and changing it to the Hearing Impaired shifts the audience and meaning of the acronym.
