The correct option is A Following braille writing.
A visually impaired person faces a lot of issues in day-to-day life. Some of them are:
1) Walking on slippery tiles without any warnings or signs.
2) Following an ordinary book is challenging, following which he/she can face issues in coping up with studies at a usual pace.
On the other hand, following the braille writing is less challenging for a blind person. He/she can feel and read the alphabets.
