Solution

Hydrogen is collected by downward displacement of water because hydrogen is insoluble in water, so it does not dissolve in water to form any compounds.

Hydrogen cannot be collected by downward displacement of air even though it is lighter than it because it forms an explosive mixture with oxygen present in the air.
