Solution
The correct option is D Longitudinal position
The best means of measuring time is by the movement of the Earth, the moon, and the planets. The Earth rotates in the eastward direction, so longitudes are the best option to know the local time of a place. At any Place, a watch can be adjusted to read the noon when the sun is at the highest point in the sky, i.e., when it is mid-day. The time shown by such a watch will give the local time for that place.Height above the sea level gives the altitude of a place, and the latitudinal position gives the north-south direction of a Place.
