Options

A. `S_(4)O_(6)^(2), S_(2) O_(3)^(2-)`
B. `S_(2) O_(7)^(2-), S_(2) O_(8)^(2-)`
C. `S_(4) O_(6)^(2-), S_(2) O_(7)^(2-)`
D. `S_(2) O_(7)^(2-)`, `S_(2) O_(3)^(2-)`

Answer

A

Explanation

`S_(4)O_(6)^(2-)impliesoverline(O)-underset(O)underset(||)overset(O)overset(||)(C)-S-S-underset(O)underset(||)overset(O)overset(||)(S)-overline(O)`
`S_(2)O_(3)^(2-)impliesoverline(O)-underset(O)underset(||)overset(S)overset(||)(S)-overline(O)`
`S_(2)O_(7)^(2-)impliesoverline(O)-underset(O)underset(||)overset(||)overset(O)overset(||)(S)-O-underset(O)underset(||)overset(O)overset(||)(S)-overline(O)`
`S_(2)O_(8)^(2-)impliesoverline(O)-underset(O)underset(||)overset(O)overset(||)(S)-O-O-underset(O)underset(||)overset(O)overset(||)(S)-overline(O)`
