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

Options

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^(+)`

Answer

D
