Option 2: It is a straight line
Option 3: It is a big circle.
Option 4: It is a curved line beyond earth.
Correct Answer: It is 180 degree longitude.
Solution : The correct answer is- it is 180 degree longitude
In the International Meridian Conference held in 1884 in Washington D.C. international date line was decided. It roughly corresponds with the 180 degree longitude of the earth. It passes mostly from the Pacific Ocean and some sparsely populated islands. It is a line from where the calendar days are demarcated. If we move from east to west in international date line we gain a day because date changes from there.
