Hint:Before answering this question you must know about some systems. In the option, they have displayed some systems in several types. For specifically the blind person can use the punctuation marks and identify the punctuation marks by touching them.It's similar to the alphabetical system, it has the same alphabetical letters as a punctuation mark.
Complete step by step answer:
Braille is a touch-reading and writing system for the blind that uses raised dots to represent the letters of the alphabet. It also includes punctuation mark equivalents as well as symbols to indicate letter groupings. Braille is read by moving the hand or hands down each line from left to right. Reading is commonly done with both hands, with the index fingers doing the majority of the work. Reading speed is around 125 words per minute on average. However, higher speeds of up to 200 words per minute can be achieved. People who are blind can review and learn the written word using the braille alphabet.
So the option (D) is correct.
Additional Information: Let us consider the another options:
Option (A):The Vedic system of education is the earliest system of education to be developed in ancient India. To put it another way, the old system of education was founded on the Vedas, which is why it was dubbed the Vedic Educational System. The Vedas are extremely important in Indian culture. Personality Development, Character Formation, Civic and Social Duties Performance, Practical Education, Preservation and Spread of Culture, and Achieving Enlightenment are the goals of Vedic education. So option (A) is wrong.
Option (B): The decimal system uses the meter, liter, and gram as length, capacity, and weight or mass units. Gabriel Mouton (1618–94), a French astronomer and mathematician, proposed the system in 1670, and it was standardized in Republican France in the 1790s. So option (B) is wrong.
Option (C): A binary system is made up of two celestial bodies that are close enough to orbit each other around a barycenter due to their gravitational pull. So the option (C) is wrong.
Note:Most importantly, braille allows blind people to read a variety of things, including recreational and instructional books, financial accounts, and restaurant menus.Various approaches for enabling blind people to read have been tried over the years. Many of them, though, were elevated copies of print letters. The braille system is widely believed to have succeeded because it is based on a logical sequence of signs designed for the fingertips rather than imitating signs designed for the eyes.
