What was the main recommendation of the States Reorganisation Commission appointed in 1953?

Boundaries of states should reflect boundaries of different languages.

The correct answer is option (1) - Boundaries of states should reflect boundaries of different languages.

The formation of Andhra Pradesh spurred the struggle for making other states on linguistic lines in other parts of the country. These struggles forced the Central Government into appointing a States Reorganisation Commission in 1953 to look into the question of redrawing the boundaries of states. The Commission in its report accepted that the boundaries of the state should reflect the boundaries of different languages. On the basis of its report, the States Reorganisation Act was passed in 1956.
