WHAT DOES NOT BELONG HERE? Give an explanation for ur answer.

Water- sun- dandelion- soil

Sparrow- ground- water- grass

H2O- CO2- CH4- SO4

Help would be very appreciated

Sparrow - ground - water - grass.

Explanation:

This option seems the most random to me. The others have to do with the environment; Water, the sun, dandelions, soil, and H2O (water), CO2 (carbon dioxide), CH4 (methane, a natural gas), and SO4 (sulfuric acid salt). I'm not sure if this is what you were looking for but I hope this helps in some fashion. :)
