Promoting balanced regional development in Assam requires:

The correct answer is: d) All of the above

Targeted investment in lagging districts is important because it can help to close the gap between the richest and poorest districts. Decentralized planning is important because it can help to ensure that local needs are met. Community participation is important because it can help to build ownership and support for development projects.

Here are some additional details about each option:

• Targeted investment in lagging districts can help to close the gap between the richest and poorest districts by providing resources and support to areas that are struggling. This can be done through a variety of means, such as providing financial assistance, building infrastructure, and investing in education and healthcare.
• Decentralized planning can help to ensure that local needs are met by giving local governments more control over development planning. This can be done by devolving power from the central government to local governments, and by providing local governments with the resources and support they need to plan and implement development projects.
• Community participation can help to build ownership and support for development projects by involving local people in the planning and implementation of these projects. This can be done through a variety of means, such as holding public consultations, forming community-based organizations, and providing training and support to local people.

It is important to note that all three of these options are interrelated. For example, targeted investment in lagging districts is more likely to be successful if it is done in conjunction with decentralized planning and community participation.
