CHEM QUES. 10 EASY POINTS! Which substance is a conductor of electricity

NaCl(s)
NaCl(l)
C6H12O6(s)
C6H12O6(l)

IF POSSIBLE A BRIEF EXPLANATION PLZ AND THANKYOU

NaCl(l) because it is ionic ( a metal and non-metal) and ionic substances only conduct electricity as a liquid. covalent (non metals only) substances never conduct electricity. pure metals always conduct elecricity

NaCl (l) I think because when it is liquid, the Na ions and Cl ions are free to move as they are delocalised, so this allows easy transfer of electricity. I think so.

NaCl(l)

The ions are mobile in NaCl(l). There are ions in NaCl(s), but they are fixed in place. The C6H12O6 has no ions at all.
