both (B) and (C)
In chemical adsorption, adsorbate and adsorbent are held together by ionic or covalent bonds.
What kind of forces exists between adsorbate and adsorbent in physisorption?
Ionic bond involves the electrostatic force of attraction between the positive and negative ions which is stronger than the force of attraction between atoms in a covalent bond.
