  1. Because they do not consist of ions

  2. Because the intermolecular force of attraction is strong

  3. Because the intermolecular force of attraction is weak

  4. Because the covalent bonds are weak

C Correct answer
Explanation

Covalently bonded molecules are seen to have strong bonds with in the molecule, but intermolecular forces are weak, which will give rise to low melting and boiling points. Ionic compounds have high melting and boiling points due to strong force of attraction between oppositely charged ions.
