Hi Heather!
a) water is not a mixture since it is a chemical substance with the chemical formula H2O
b) air is a mixture of gases and it is mainly composed of nitrogen, oxygen, carbon dioxide and argon
c) methane is not a mixture since it is a chemical substance with the chemical formula CH4
d) magnesium is not a mixture since it is a chemical element (metal) with the chemical formula Mg

The Air (as in what we breathe) is a mixture because it's composed of Nitrogen(78%) and Oxygen(20%) and the other 2% is argon and other gases.
