Many languages in J&K are considered endangered due to:

The correct answer is: All of the above.

Many languages in Jammu and Kashmir are considered endangered due to a number of factors, including migration, preference for official languages, and lack of standardization.

• Migration: The migration of people from other parts of India to Jammu and Kashmir has led to the decline of many local languages. This is because the migrants often bring their own languages with them, which are then used in schools and other public institutions. As a result, the local languages are often seen as being less important, and their use declines.
• Preference for official languages: The official languages of Jammu and Kashmir are Hindi and English. These languages are used in government and education, and they are seen as being more prestigious than the local languages. This can lead to people preferring to use the official languages, rather than their own local languages.
• Lack of standardization: Many of the languages spoken in Jammu and Kashmir do not have a standardized written form. This can make it difficult for people to learn these languages, and it can also lead to them being seen as being less important.

All of these factors have contributed to the decline of many languages in Jammu and Kashmir. It is important to take steps to protect these languages, such as promoting their use in schools and other public institutions, and developing standardized written forms for them.
