The correct options are
B water repellants
C water absorbents
Hydrophilic molecules are water absorbents while hydrophobic molecules are water repellants. For example, the two ends of a soap molecule are hydrophilic and hydrophobic in nature. The hydrocarbon chains are non-polar and hydrophobic in nature, they attach themselves to the oil/ grease stains. The ionic end is hydrophilic in nature and it aligns with the water molecules.
