Prime Meridian
Tropic of Cancer
Equator
Which of the above lines is/are a Great Circle?
1, 2 and 3

Explanation: A Great Circle is any circle that divides the globe into two equal halves and has the same center and radius as the Earth.
Equator is the only line of latitude that is a Great Circle.
Prime Meridian and other meridians form Great Circles only when combined with their opposite meridians, not individually.
Tropic of Cancer is a small circle and not a Great Circle.
