Which of the following best describes the prime meridian?

A. The meridian at which longitude is defined to be 0 degrees
B. The only line of latitude that is also a great circle
C. The only line of longitude that is also a great circle
D. The location of a place on Earth north or south of the Equator

Longitudes are imaginary lines going from south pole to north pole. These lines are known as meridians. Zero degrees longitude is an imaginary line known as the Prime Meridian or the Greenwich meridian.
The Prime meridian acts as the starting point for measuring distance both east and west around the Earth. The meridian runs through Greenwich, England and is internationally accepted as the line of 0 degrees longitude.
The lines of all longitudes or meridians are great circles, unlike in the case of lines of latitude where only the equator is a great circle.

A prime meridian is a meridian at which longitude is defined as 0°. Option A is correct. The meridian at which longitude is defined to be 0 degrees best describes the prime meridian.

What is prime meridian?

In a geographic coordinate system, a prime meridian is a meridian at which longitude is defined as 0°. A great circle is formed when a prime meridian and its anti-meridian are joined together.

Longitudes are imaginary lines that connect the south and north poles. Meridians are the names given to these lines.

The Prime Meridian is used to measure distances east and west around the Earth. In contrast to lines of latitude, where only the equator is a great circle, all longitudes or meridians are great circles.

Hence option A is correct. The meridian at which longitude is defined to be 0 degrees best describes the prime meridian.
