b.
They have low melting and boiling points.
c.
They are good electrical conductors in all phases.

2 Answer

  • The answer is C. because covalent compounds don't transfer electrons like ionic compounds unless they react. Also, covalent compounds are all nonmetal elements and nonmetals aren't good electric conductors. So, therefore, covalent compounds are not good electric conductors. 
  • c they are good electrical conductors in all phases
