D. 1, 2, 3, 4 and 5D. 1, 2, 3, 4 और 5

Explanationव्याख्या

All five statements are correct according to the source.
World Braille Day is observed globally on 4 January to commemorate the birth of Louis Braille, inventor of the tactile reading and writing code that bears his name.
The source identifies Louis Braille as a Frenchman who lived from 1809 to 1852 and lost his sight at the age of three.
At the age of ten, he received a scholarship to the Royal Institute for Blind Youth in Paris.
It was there that he developed the Braille system after being inspired by an earlier military communication method known as 'night writing'.
According to the source, this night-writing system was created by Charles Barbier de la Serre in 1815.
It used 12 raised dots and had been developed so soldiers could communicate silently in darkness.
Braille simplified the concept into a system using six raised dots arranged in a 3 × 2 matrix.
Different combinations of these raised dots create distinguishable characters.
The source notes that Braille can be produced using slates, Braille writers and electronic devices.
It also stresses that despite artificial intelligence and voice technologies, Braille remains important for independence, especially among people who are congenitally blind.
Exam revision should connect: World Braille Day → 4 January → Louis Braille → France → lost sight age 3 → Royal Institute Paris age 10 → Charles Barbier's night writing → 1815 → 12 dots → Braille → 6 dots in 3×2 matrix.
Since all statements reproduce information in the source, option D is correct.

सभी पाँच statements source के अनुसार सही हैं। World Braille Day globally 4 January को observed किया जाता है और यह Louis Braille की birth को commemorate करता है। Louis Braille वह inventor थे जिन्होंने blind और visually impaired persons के लिए tactile reading and writing code develop किया। Source के अनुसार Louis Braille 1809-1852 के बीच जीवित रहे, France में born हुए और age three पर उनकी eyesight चली गई। Age ten पर उन्हें Royal Institute for Blind Youth, Paris में scholarship मिली। यहीं उन्होंने Braille system develop किया, जिसके लिए inspiration एक military communication system 'night writing' से मिली। Source के अनुसार 'night writing' Charles Barbier de la Serre ने 1815 में बनाया था। इसमें 12 raised dots use किए जाते थे और soldiers को darkness में silently communicate करने के लिए design किया गया था। Braille ने concept को simplify करके six raised dots का system बनाया जो 3 × 2 matrix में arranged होते हैं। Different combinations से characters form होते हैं। Source यह भी बताता है कि Braille slates, Braille writers और electronic devices के माध्यम से लिखा जा सकता है। AI और voice technologies के rise के बावजूद Braille independence के लिए crucial बना हुआ है। Revision: 4 Jan → Louis Braille → France → sight lost at 3 → Royal Institute Paris → Barbier 1815 → night writing 12 dots → Braille 6 dots, 3×2। इसलिए option D सही है।
