The equalitative sketches I, II and III ...

The equalitative sketches I, II and III given below show the variation of surface tension with molar concentration of three diferent aqueous solutions of `KCl, CH_(3)OH` and `CH_(3)(CH_(2))_(11)OSO_(3)^(-)Na^(+)` at room temperature.

The correct assignment of the sketches is

A

`I:KCl, II:CH_(3)OH, III:CH_(3)(CH_(2))_(11)OSO_(3)^(-)Na^(+)`

B

`I:CH_(3)(CH_(2))_(11)OSO_(3)^(-)Na^(+), II:CH_(3)OH, III:KCl`

C

`I:KCl, II:CH_(3)(CH_(2))_(11)OSO_(3)^(-)Na^(+), III:CH_(3)OH`

D

`I:CH_(3)OH, II:KCl, III :CH_(3)(CH_(2))_(11)OSO_(3)^(-)Na^(+)`
