Answer

Brief Explanations:

Covalent substances have weaker intermolecular forces compared to ionic substances. Ionic substances are held together by strong electrostatic forces between ions, while covalent substances have weaker van - der - Waals forces or hydrogen bonds (in some cases). Weaker intermolecular forces in covalent substances mean they generally have lower melting points.

Answer:

C. Covalent substances have weaker intermolecular attractions.
