All of the above given following are possible longitude coordinates except W 181 °
Answer: Option C
Step-by-step explanation:
A longitudinal coordinate is a geographical coordinate that specifies a particular position of a point in either west or east of the earth's surface and not specifying the direction in the east or west does not complete a longitudinal coordinate.
Only W 181 °degrees does not provide any longitudinal coordinates because W 181 ° is doesn't exist and all the coordinates of the longitude show some direction either in the west or in the east so the option c is not a longitudinal coordinate.
