Model Answer
(c) (ii) and (iv)
Carbon compounds are bad conductors of electricity and have weak intermolecular forces of attraction (evidenced by their low melting and boiling points).
Explanation
The passage states: "covalent compounds are generally poor conductors of electricity" and "inter-molecular forces are weak… giving rise to low melting and boiling points." So statements (ii) and (iv) are both correct. Examiners expect you to recall these two key properties of covalent/carbon compounds together.
