Correct Option (B)
Statements 2 and 3 are the most logical and rational inferences from the passage.
Statement 2: The passage explicitly states that increasing food wastage results in land degradation by approximately 45%, primarily due to deforestation, unsustainable agricultural practices, and excessive groundwater extraction. This directly implies an adverse effect on land productivity.
Statement 3: The passage mentions that the energy expended on wasted food leads to the production of about 3.5 billion tonnes of carbon dioxide annually, along with other harmful gases. Therefore, a reduction in food loss and wastage would consequently lead to a decrease in the carbon footprint.
Incorrect Options:
Statement 1: The passage indicates that food loss and wastage occur "throughout the supply chain, from initial agricultural production to final household consumption." This comprehensive scope contradicts the assertion that current methods of food distribution are solely responsible.
Statement 4: The passage emphasizes the criticality of addressing food loss and wastage but does not state or imply that post-harvest technologies to prevent or reduce such losses are unavailable. The absence of a statement about technology availability cannot be inferred as its non-existence.
