Final answer:
Wax is the hydrophobic material out of the options given. Paper is not a hydrophobic material because it can absorb water.
Step-by-step explanation:
Out of the options given, wax is the hydrophobic material. Waxes are made up of long fatty acid chains esterified to long-chain alcohols, and their hydrophobic nature prevents water from sticking on the surface. On the other hand, paper is not a hydrophobic material because it is primarily made up of cellulose fibers which have hydrophilic properties and can absorb water.
