Answer 1

The correct option is C Both statements are true and Statement 1 is responsible for Statement 2.

The Earth rotates around its polar axis. The axis is not perpendicular to the axis of revolution. It is tilted at an angle of 23 ½ degrees. This tilt in the axis brings variation in the length of day and night around the northern and southern poles.
