The International Date Line is made zigzag to avoid which one of the following island groups?

The International Date Line (IDL) is an imaginary line on Earth's surface that defines the boundary between one day and the next. It roughly follows the 180° meridian but is not straight; it zigzags to avoid cutting through political borders or island groups, ensuring they share the same calendar day. One of the primary deviations occurs in the North Pacific, where the line bends westward to avoid the Aleutian Islands. This allows the islands, which are part of Alaska (USA), to maintain the same date as the rest of the United States. Other significant deviations occur at the Bering Strait to keep Russia and Alaska on separate sides, and in the South Pacific to accommodate the island nations of Kiribati, Fiji, and Tonga.
