The correct answer is: All of the above.

Traditional painting techniques in Arunachal Pradesh are facing challenges due to a number of factors, including:

• Lack of documentation: Many of these techniques have not been documented, making it difficult to preserve them.
• Modernization and changing lifestyles: As people in Arunachal Pradesh adopt more modern lifestyles, they are less likely to practice traditional painting techniques.
• Limited availability of natural materials: Some of the natural materials used in traditional painting techniques are becoming increasingly scarce.

These challenges are leading to a loss of traditional knowledge and skills, and could eventually lead to the extinction of these unique painting techniques.

Here is a brief explanation of each option:

• Lack of documentation: Many of the traditional painting techniques in Arunachal Pradesh have not been documented. This means that there is no written record of how these techniques are performed, making it difficult to preserve them. Without documentation, it is also difficult to teach these techniques to new generations.
• Modernization and changing lifestyles: As people in Arunachal Pradesh adopt more modern lifestyles, they are less likely to practice traditional painting techniques. This is because modern lifestyles often require people to spend more time working and less time on leisure activities such as painting. Additionally, modern lifestyles often involve exposure to Western culture, which can lead people to view traditional painting techniques as outdated or irrelevant.
• Limited availability of natural materials: Some of the natural materials used in traditional painting techniques are becoming increasingly scarce. This is due to a number of factors, including deforestation, climate change, and overexploitation. As these materials become more difficult to obtain, it becomes more difficult to practice traditional painting techniques.

These challenges are leading to a loss of traditional knowledge and skills, and could eventually lead to the extinction of these unique painting techniques. It is important to take steps to preserve these techniques, such as documenting them, teaching them to new generations, and promoting their use.
