The type of change that has occurred on mixing ice cubes, water ,sugar, koolaid mix is a physical change.
Physical changes are defined as those changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to further simpler compounds.
Physical changes are always reversible by using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible changes and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

D. Hydrogen
Answer is: C. nitrogen.
Together, nitrogen (N₂) and oxygen (O₂) by volume account for 99.03% volume of the gases composing the dry air in the lower atmosphere.
Volume of nitrogen in air is 78.08%.
Volume of oxygen in air is 20.95%.
Together: 78.08% + 20.95% = 99.03%.
This gases can be separated by fractional distillation of liquefied air.
