The correct answer is C) 1 and 4. Statements 1 and 4 regarding laterite soils are correct, while statements 2 and 3 are incorrect.
Laterite soils are formed under conditions of high temperature and heavy rainfall, leading to intense leaching. This process removes silica but leaves behind iron and aluminium oxides, which give the soil its characteristic red colour (Statement 1). These soils are generally poor in nutrients like nitrogen, potash, lime, and organic matter (Statement 2 incorrect). They are found in specific regions experiencing such climate, primarily in the Western and Eastern Ghats, parts of southern Maharashtra, Karnataka, Kerala, Tamil Nadu, Odisha, etc., not typically Rajasthan and UP (Statement 3 incorrect). Despite being infertile, certain crops like tapioca and cashew nuts grow well on them with appropriate fertilization (Statement 4).
