- A3 and 4
- B1, 3 and 4
- COnly 4
- D1, 2 and 3
Explanation
Statement 1 is wrong because Northern Hemisphere cyclones spin counter-clockwise; statement 2 is wrong because the north-east trades blow from the north-east toward the equator, not toward the north-west. Statement 3 is correct since Southern Hemisphere anticyclones spin counter-clockwise, and statement 4 is correct because both the westerlies and the trade winds originate from the sub-tropical highs. Hence statements 3 and 4 are correct.
