{'atmosphere': [1, 1, 4, 7], 'carbon monoxide': [3, 0, 1, 1], 'ozone': [3, 0, 3, 5], 'biomass residue': [0, 0, 0, 1], 'sulphur dioxide': [0, 0, 0, 1], 'burning': [1, 0, 1, 2], 'crop': [0, 0, 1, 1]}
The correct answer is (d) 1, 2, 3 and 4.
All of the above gases can be released into the atmosphere due to the burning of crop/biomass residue. Carbon monoxide and methane are produced due to incomplete combustion, ozone is formed due to the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight, and sulphur dioxide is produced due to the presence of sulphur in the biomass. These emissions can have harmful effects on both human health and the environment.
