Option 1 states that the Malwa region is drained by the tributaries of the Sone river. This statement is incorrect. The Malwa region is actually drained by the main tributaries of the Narmada and Tapti rivers, not the Sone river. Therefore, option 1 is incorrect.
Option 2 states that the Chotanagpur region is drained by the tributaries of the Mahanadi river. This statement is also incorrect. The Chotanagpur region is drained by the tributaries of the Subarnarekha, Koel, and Damodar rivers, not the Mahanadi river. Therefore, option 2 is incorrect.
Since both statements, 1 and 2, are incorrect, the correct answer is option 4 - Neither 1 nor 2.
In summary, neither the Malwa region nor the Chotanagpur region are drained by the stated rivers in the options.
