Sodium + Oxygen Which atom is transferring (giving up) electron(s)?
How many electrons are being transferred? What charge does this give the positive ion? How many electrons is the negative ion accepting?
What will be the charge of the negative ion? What is the overall charge of the compound?​

i would say b

explanation:

but i think i would need more information than that

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
