D2 & 4 only
Correct answer: (C) 1, 2 & 3 only
Explanation
Northern Hemisphere carbon dioxide is higher because it has more land, the south has more ocean, and more fossil fuel is burned in the north.
Statement 1 is true, as the Northern Hemisphere holds most of the world's land mass.
Statement 2 is true, since the Southern Hemisphere is dominated by ocean.
Statement 3 is true, because most industry and fossil fuel burning occur in the north.
Statement 4 is false, as the Northern Hemisphere is not colder than the southern one.
Oceans absorb carbon dioxide, so the ocean-rich south draws down more of the gas.
