The correct answer is: B) Decentralized development.
Special incentives provided to industries located in less-developed regions of Karnataka aim to promote decentralized development. This means that the government wants to encourage businesses to set up shop in smaller towns and villages, rather than just in the major cities. This can help to reduce inequality and improve the quality of life in rural areas.
Option A, urbanization, is incorrect because the government is not trying to encourage people to move to cities. In fact, they are trying to encourage people to stay in rural areas.
Option C, migration to cities, is incorrect for the same reason as option A.
Option D, skill development only, is incorrect because the government is not just trying to develop skills. They are also trying to encourage businesses to set up shop in rural areas.
