Answer: (c) I, II, and III Explanation: • Statement I: Direct Air Capture (DAC) removes CO₂ from the atmosphere, which can be stored underground or used, making it a method of carbon sequestration. This is correct. • Statement II: Captured CO₂ from DAC can be used in producing plastics (e.g., polycarbonates) and in food processing (e.g., carbonation in beverages), so this is correct. • Statement III: DAC provides CO₂ that can be combined with hydrogen to produce synthetic fuels for aviation, reducing carbon emissions. This is correct. All three statements are accurate, so the answer is (c)
