Disparities in development exist between different districts in Assam due to factors like:

The correct answer is: d) All of the above.

Geography, historical legacies, and resource allocation are all factors that contribute to disparities in development between different districts in Assam.

• Geography can affect development in a number of ways. For example, districts that are located in remote areas or that have difficult terrain may be more difficult to access and develop. Additionally, districts that are located in areas with a lot of natural resources may be more likely to experience economic development.
• Historical legacies can also affect development. For example, districts that were historically ruled by different empires or kingdoms may have different cultures and traditions, which can impact their development. Additionally, districts that were affected by war or natural disasters may have difficulty recovering and developing.
• Resource allocation can also affect development. For example, districts that receive more government funding for development may be more likely to experience economic growth. Additionally, districts that have a higher concentration of educated workers may be more likely to attract businesses and investment.

It is important to note that these are just some of the factors that can contribute to disparities in development. There are many other factors that can play a role, such as population density, climate, and political stability.
