for me, it's letter C, earth's tilt ,the earth's tilted must be the cause of change of length day, if earth's axis was not tilted, each night and day everywhere on Earth would always be 12 hours long and and there would no season at all.

the earths tilted must be the caused of the length of the day so my answer is letter C. earth's tilt.
