In the map given below, four islands of Indian Ocean region i.e. (A) Seychelles, (B) Chagos, (C) Mauritius and (D) Socatra are marked as 1, 2, 3 and 4. Match them and select the correct answer from the codes given below.

Geographically, these four islands in the Indian Ocean can be identified based on their latitudinal and longitudinal positions:

• Socotra (D): Located near the Horn of Africa/Yemen, it is the northernmost island in the group. On the map, it corresponds to marker 2.
• Mauritius (C): Located east of Madagascar, it is the southernmost island among the four. It corresponds to marker 4.
• Seychelles (A): Located north of Madagascar and west of the Chagos Archipelago. Being further west and slightly north of Chagos, it is marked as 1.
• Chagos (B): Located in the central Indian Ocean, east of the Seychelles. It is marked as 3.

Therefore, the correct mapping is A:1, B:3, C:4, and D:2, which matches Option A.
