1. A

   4 2 1 3

   4 2 1 3 would put Mount Etna in Mexico and Paricutin in Italy. Etna is in Italy and Paricutin (Parícutin) is in Mexico, so this code swaps those two. This option is not the key.

2. B

   4 1 2 3

   4 1 2 3 is the official key: Mount Rainier–U.S.A., Mount Etna–Italy, Mount Paricutin–Mexico, Mount Apo–Philippines. Rainier is a Cascade stratovolcano in Washington State. Etna is on Sicily. Parícutin is the famous cinder cone that grew in a Mexican field. Apo is the highest peak of the Philippines. That matching is (b).

3. C

   2 1 4 3

   2 1 4 3 starts by placing Rainier in Mexico and Apo’s partner wrongly. This option is therefore wrong.

4. D

   4 3 2 1

   4 3 2 1 gives Etna to the Philippines and Apo to Italy. This option is not the key.

Summary. Official key is (b) 4 1 2 3. Rainier is in the United States, Etna in Italy, Paricutin in Mexico and Apo in the Philippines. Codes that swap Italy with Mexico or with the Philippines fail. Only (b) maps List-I onto List-II correctly.
