The odd one among the four options is water.
This is because, all three, namely milk, alloy and air are mixture.
Only water among the four options is a compound which is made of the elements oxygen and hydrogen.
One molecule of water consists of two atoms of hydrogen and one atom of oxygen.
So water is the odd one.
