The correct answer is B. most.
The word “most” is the most appropriate word to use in the sentence “It should be the aim of every educated Indian to see that as most as possible people become literate.” This is because the sentence is about the importance of education and literacy, and the word “most” conveys the idea that everyone should have the opportunity to learn and be literate.
The other options are not as appropriate. The word “few” suggests that only a small number of people should be literate, which is not the goal of education. The word “many” is also not as strong as “most,” and it does not convey the same sense of urgency. The word “much” is not appropriate because it is a measure of quantity, not quality.
In conclusion, the correct answer is B. most.
