Braille is primarily known as a tactile writing system that allows individuals who are blind or visually impaired to read and write using raised dots that correspond to letters and characters. This system is designed specifically for those who cannot rely on vision to access written text, making it an essential tool for literacy and education among the blind. The arrangement of dots is understood through touch, enabling users to read by moving their fingers over the Braille characters.

The other options do not capture the primary purpose of Braille. For example, while visual aids and digital communication tools are valuable, they do not specifically address the needs of individuals who cannot see at all. Similarly, emotional expression can take many forms, but it does not encompass the primary function of Braille as a writing and reading system designed for accessibility. Thus, option B accurately reflects the essential role of Braille in providing a means of communication and literacy for blind individuals.
