A. `S_(2)O_(4)^(2-) lt SO_(3)^(2-) lt S_(2)O_(6)^(2-)`
B. `SO_(3)^(2-) lt S_(2)O_(4)^(2-) lt S_(2)O_(6)^(2-)`
C. `S_(2)O_(4)^(2-) lt S_(2)O_(6)^(2-) lt SO_(3)^(2-)`
D. `S_(2)O_(6)^(2-) lt S_(2)O_(4)^(2-) lt SO_(3)^(2-)`

Answer 1

Correct Answer - A
`overset(+3)(S_(2)) O_(4)^(-2) lt overset(+4)(S)O_(3)^(-2) lt overset(+5)(S_(2))O_(6)^(-2)`
