The cultivation of cotton in Karnataka is mainly concentrated in which region?

Northern plains
Coastal plains
Southern transitional zone
Malnad

The correct answer is: C) Southern transitional zone.

The southern transitional zone is a region in Karnataka that is located between the Western Ghats and the Eastern Ghats. It is a region of high rainfall and is well-suited for the cultivation of cotton. The other options are incorrect because:

  • The northern plains are a region of low rainfall and are not well-suited for the cultivation of cotton.
  • The coastal plains are a region of high rainfall, but they are also a region of high salinity and are not well-suited for the cultivation of cotton.
  • Malnad is a region of high rainfall and is well-suited for the cultivation of coffee, but it is not well-suited for the cultivation of cotton.
