D
2 3 1 4
Correct answer: (d) 2 3 1 4
Explanation
- A
3 4 1 2
Code 3 4 1 2 would give Willy-willies to Japan and Taifu to the USA. Willy-willies are Australian; the code is wrong.
- B
2 3 4 1
2 3 4 1 assigns Baguio to the USA and hurricanes to the Philippines. Baguio is the Philippine name; hurricanes are Atlantic/USA.
- C
1 3 2 4
1 3 2 4 gives Willy-willies to the Philippines and Baguio to Australia — swapped.
- D
2 3 1 4
Willy-willies — Australia (2); Taifu — Japan (3); Baguio — Philippines (1); Hurricanes — USA (4). Code 2 3 1 4 is the official key.
Summary. Official key is (d) 2 3 1 4. Regional names: willy-willy (Australia), taifu (Japan), baguio (Philippines), hurricane (USA/Atlantic).
