Result
Your answer: —  Â·  Correct: C
Explanation

The correct option is C (1 and 3 only) based on the following geographical facts:

  • Statement 1 is correct: Tropical cyclones require warm sea surface temperatures (above 26.5°C) and low vertical wind shear. These conditions are rarely met in the South Atlantic and eastern South Pacific due to cooler waters and high wind shear, making cyclone formation extremely rare there.
  • Statement 2 is incorrect: Tropical cyclones in the North Atlantic and eastern North Pacific are called Hurricanes. The term Typhoon is specifically used for storms in the Northwest Pacific Ocean (near East Asia).
  • Statement 3 is correct: The term Cyclone is used for these storms in the Indian Ocean and the South Pacific Ocean (including the waters around Australia).
