{'laterite soils': [1, 0, 0, 3], 'soils': [3, 0, 1, 1], 'nitrogen': [1, 1, 0, 2], 'rajasthan': [0, 0, 1, 18], 'india': [8, 1, 7, 13], 'nuts': [0, 0, 0, 1]}

The correct answer is "1 and 4."

1. They are generally red in color: This statement is correct. Laterite soils in India are typically reddish or brownish-red in color due to the presence of iron oxides.

2. They are rich in nitrogen and potash: This statement is incorrect. Laterite soils are generally leached and deficient in nutrients, including nitrogen and potash. They are often characterized by low fertility.

3. They are well-developed in Rajasthan and UP: This statement is incorrect. Laterite soils are not well-developed in Rajasthan and Uttar Pradesh (UP). These states are known for other types of soils, such as alluvial soils in Uttar Pradesh and arid desert soils in Rajasthan.

4. Tapioca and cashew nuts grow well on these soils: This statement is correct. Despite their low fertility, laterite soils can support the growth of certain crops, including tapioca (cassava) and cashew nuts.

Therefore, the correct answer is "1 and 4."
