Statement (c) with regard to the winter solstice is correct. Known as midwinter, it is an astronomical phenomenon marking the day with the shortest period of daylight and the longest night of the year. In the Northern Hemisphere, this is the December solstice and in the Southern Hemisphere, this is the June solstice. The farther north from the equator we are, the lesser sunlight we will get during the solstice and the longer the night will be. The sun in the sky is farthest south in the Northern Hemisphere (December 21 or 22). So, it experiences 24 hours of darkness
