Which of the following is an Audio-Aids?

Correct option is A

Audio aids are learning tools that enhance the educational experience by stimulating the auditory system. They target auditory learners, improve listening and communication skills, and provide a better understanding of the subject through sound-based learning.
The Linguaphone is a well-known audio-aid that has been a pioneer in language learning. It employs the "Listen, Understand, Speak" methodology, allowing learners to develop language skills systematically. Students first listen to the language content, comprehend it, and then practice speaking. This self-study tool is beneficial for auditory learners and has been globally used for language training since 1901.
Other options, such as Overhead Projectors, Epidiascopes, and Bulletin Boards, are visual or visual-physical aids, not audio-based.
