{'farming practice': [0, 0, 0, 1], 'farmer': [0, 1, 1, 1], 'farm': [0, 0, 0, 1], 'organic fertilizers': [1, 0, 1, 1], 'crop rotation': [1, 0, 0, 0], 'tree belt': [0, 0, 0, 1], 'environment': [2, 0, 0, 3], 'large scale irrigation system': [0, 0, 0, 1], 'practices': [1, 0, 1, 7]}

The correct answer is option 2: 1, 2, and 4.

Option 1, planting a tree belt, is an environmentally friendly practice. Tree belts can help prevent soil erosion, provide shade to crops, and create habitat for wildlife.

Option 2, practicing crop rotation, is also a sustainable farming practice. Crop rotation helps improve soil health, reduces the risk of pests and diseases, and enhances nutrient cycling in the field.

Option 3, carrying out a large scale irrigation system, is not considered as environmentally friendly. Large-scale irrigation systems can lead to water scarcity, depletion of groundwater resources, and salinization of soil.

Option 4, using organic fertilizers, is another environmentally friendly practice. Organic fertilizers are derived from natural sources and do not contain synthetic chemicals that can harm the environment or contaminate water sources.

In conclusion, options 1, 2, and 4 are practices that can justify the farmer`s claim of being environmentally friendly, while option 3 is not.
