C) ?Both 1 and 2???? ???????????
D) ?Neither 1 nor 2
Correct Answer: A
Solution :
?Difference in duration of days and nights increases from equator towards the poles because inclination of various latitudes towards the sun increases away from the equator. At the time of summer solstice, the earth's North Pole has the maximum inclination towards the sun and days become longer as we move away from the equator towards the North Pole. At the time of winter solstice. South Pole in inclined towards the sun and days are longer in the southern hemisphere. The circle of illumination divides the equator into two equal parts in all the seasons of the year and the duration of days and nights does not change with the change in seasons.
