International Date Line passes through which of the following ?

The International Date Line (IDL) is an imaginary line of demarcation on the Earth's surface that separates two consecutive calendar dates [t1]. It is located approximately at the 180th meridian, which is halfway around the world from the Prime Meridian in Greenwich [c1][t3]. The IDL passes through the mid-Pacific Ocean, running from the North Pole to the South Pole [t1][t8]. It is drawn in a zig-zag manner to avoid dividing island nations or landmasses into two different dates, specifically curving at the Bering Strait and around island groups like Polynesia, Melanesia, and Micronesia [c2][c3]. While the Prime Meridian passes through the Atlantic Ocean and countries like the UK and Ghana [t7], the IDL is situated roughly in the center of the Pacific Ocean to minimize administrative confusion [t7]. Therefore, among the given options, the Pacific Ocean is the correct geographical feature it traverses.
