The correct answer is: b) Vulnerable languages.
A vulnerable language is a language that is spoken by a small number of people and is at risk of becoming extinct. Vulnerable languages are often spoken in remote areas, and their speakers may be under pressure to adopt a more widely spoken language. This can happen for a number of reasons, such as economic development, government policies, or the spread of education.
In Arunachal Pradesh, there are a number of languages that are spoken by only a few thousand people. These languages are at risk of becoming extinct, as their speakers are increasingly adopting Hindi or English. This is a cause for concern, as the loss of a language means the loss of a unique culture and way of life.
Here is a brief explanation of each option:
- Extinct languages are languages that are no longer spoken by anyone. There are a number of reasons why a language might become extinct, such as the death of all its speakers or the loss of its speakers’ community.
- Official languages are languages that are recognized by the government as being the official language of a country or region. Official languages are often used in government, education, and the media.
- Widely spoken languages are languages that are spoken by a large number of people. Widely spoken languages are often used in international communication and trade.
