Detailed explanation-1: -The statement regarding the duration of day and night that is correct is-Difference is least near the Equator and progressively increases away from it.
Detailed explanation-2: -Due to the axial tilt of the Earth of an angle of approximately 23 degrees, there is variation in the duration of days and nights across the globe. This is due to difference in intensity of Sun’s rays falling on different parts of the globe.
Detailed explanation-3: -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.
Detailed explanation-4: -The Earth and sun are part of the solar system, with the sun at its centre. An Earth day is 24 hours because the Earth spins on its axis once every 24 hours. At any one time half of the Earth’s sphere is in sunlight (day) while the other half is in darkness (night).
