Correct Answer : Option c

Explanation
Statement 1 is correct: Unlike parallels of latitude, all meridians are of equal length. Thus, it was difficult to number the meridians. Therefore, all countries decided that the count should begin from the meridian that passed through Greenwich, where the British Royal Observatory is located. This meridian is called the Prime Meridian. Its value is 0° longitude, and from it, we count 180° eastward as well as 180° westward. The Prime Meridian and the 180° meridian divide the Earth into two equal halves, the Eastern Hemisphere and the Western Hemisphere. It is, however, interesting to note that the 180° East and 180° West meridians are on the same line.

Statement 2 is correct: When the sun is at its highest point in the sky at the Prime Meridian of Greenwich, all places along this meridian will have noon. This is because all places on the same meridian have the same local time.
