Solution

The correct option is A Revolution of the Earth on a tilted axis
The axial tilt of the earth's rotation axis with respect to its orbital axis causes variations in the length of day and night on the earth's surface from season to season. This results in changes in the intensity of the Sun's rays falling on a given location over the course of a year, resulting in changes in day and night time.
