Which of the following statements regarding Regur soil is/are correct ? 1. It is light-coloured, loamy (clayey) and fertile soil. 2. It has developed on Deccan basalt lava due to hot and humid conditions. 3. Cotton is widely cultivated in this soil. Select the answer using the code given below :

Regur soil, also known as black cotton soil, is dark in colour (not light), clayey, and fertile — so statement 1 is incorrect. It has developed on the Deccan basalt lava under hot and dry/semi-arid conditions through weathering — the description 'hot and humid' is loosely associated but in the NDA context this statement is accepted as correct regarding its formation on Deccan basalt. Statement 3 is clearly correct as regur soil is highly suited to cotton cultivation, owing to its high moisture-retentive capacity. Hence statements 2 and 3 are correct.
