ОВ.
simple sugar (C6H1206)
OC.
table salt (NaCl)
OD.
carbon dioxide (CO2)

table salt NaCl

option C

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
