Answer is Option C. -> 3 2 1 5 4
Answer: (c) A prime meridian is a meridian (a line of longitude) in a geographical coordinate system at which longitude is defined to be 0°. A prime meridian and its opposite in a 360°-system, the 180th meridian (at 180° longitude), form a great circle. This great circle divides the sphere, e.g., the Earth, into two hemispheres. The Tropic of Cancer also referred to as the Northern Tropic, is the most northerly circle of latitude on the Earth at which the Sun may appear directly overhead at its culmination. The International Date Line (IDL) is an imaginary line of longitude on the Earth’s surface located at about 180 degrees east (or west) of the Greenwich Meridian. Arctic Circle is an imaginary circle around the earth, parallel to the equator, at latitude66° 32' N; it marks the northernmost point at which the sun appears above the level of the horizon on the winter solstice. Tropic of Capricorn is the parallel of latitude that is approximately $23 1/2$ degrees south of the equator and that is the southernmost latitude reached by the overhead sun 40.
