Concept:
- A valid inference must be supported by the stated evidence and must not introduce a new topic.
- Translate observed consumer behaviour into the minimum conclusion needed to explain it.
Step 1: Isolate the consumer evidence.
Consumers increasingly seek organic products because they are concerned about chemical residues and environmental harm.
Step 2: Infer the smallest supported conclusion.
Choosing products for those reasons shows growing awareness of how food production affects health and the environment.
This is exactly the claim in option E.
Step 3: Apply the no-new-topic test.
Profitability, crop-yield uncertainty, and government subsidies are not discussed. The claim that all consumers prefer organic food is also too broad.
Therefore, options A, B, C, and D go beyond the evidence.
Final Answer: Consumers are becoming more aware of the environmental and health implications of food production, option E.
