Complete answer:

The climate of Earth is the layer of gases, usually known as air, held by Earth's gravity, encompassing the planet Earth and framing its planetary air. The air of Earth secures life on Earth by making pressure taking into account fluid water to exist on the Earth's surface, engrossing bright sun oriented radiation, warming the surface through warmth maintenance (nursery impact), and lessening temperature limits among day and night (the diurnal temperature variety).
The significant constituent of air is nitrogen. Air comprises 78% nitrogen, 21% oxygen and 1% of different gases, dust, pollution, water fume.
So, option (c) is correct.
