Show answer and explanation

Correct answer: (C) van der Waals bonds

Explanation

In the conventional bonding-strength comparison intended here, hydrogen bonds are stronger than ordinary van der Waals interactions but weaker than primary ionic, metallic and covalent bonds. Thus C. Specific bond energies vary by substance, so this is the usual category-level comparison.
