Answer

Brief Explanations:

Ionic substances are held together by strong ionic bonds between ions, while covalent substances have weaker intermolecular forces like London - dispersion forces, dipole - dipole forces, or hydrogen bonds between their molecules. These weaker intermolecular forces in covalent substances make them have lower melting points compared to ionic substances.

Answer:

C. Covalent substances have weaker intermolecular attractions.
