Challenges faced by traditional institutions in Manipur include:

Erosion of authority
Influence of modern governance systems
Lack of recognition by state laws
All of the above

The correct answer is: All of the above.

Traditional institutions in Manipur are facing a number of challenges, including erosion of authority, influence of modern governance systems, and lack of recognition by state laws.

Erosion of authority: Traditional institutions have been losing their authority over time, as people have become more educated and exposed to modern ideas. This has led to a decline in the respect for traditional leaders and institutions.

Influence of modern governance systems: Modern governance systems have also had a significant impact on traditional institutions. The state government has taken over many of the functions that were traditionally performed by traditional institutions, such as dispute resolution and law enforcement. This has led to a decline in the power and influence of traditional institutions.

Lack of recognition by state laws: Traditional institutions are not recognized by state laws in Manipur. This means that they have no legal status and cannot enforce their decisions. This has made it difficult for traditional institutions to function effectively.

These challenges are having a negative impact on traditional institutions in Manipur. They are making it difficult for these institutions to play their traditional role in society. This is a concern, as traditional institutions play an important role in maintaining social order and cohesion.
