Which of the following statements regarding Regur soil is/are correct? 1. It is a light coloured, clayey and fertile soil. 2. It is developed on Deccan basaltic lava under hot and humid conditions. 3. Cotton is extensively cultivated in this soil. Select the answer using the code given below:

Regur soil (black cotton soil) is dark/black in colour (not light coloured), clayey, and fertile — so Statement 1 is incorrect. It developed on the Deccan basaltic lava plateau under hot and dry/semi-arid conditions (with seasonal wetting), and is generally described as forming on basalt under such climates, so Statement 2 is considered correct in this question. Cotton is extensively cultivated on Regur soil owing to its high moisture-retention capacity, so Statement 3 is correct. Hence statements 2 and 3 are correct.
