The qualitative sketches I, II and III given below show the variation of surface tension with molar concentration of three different aqucous solutions of \( \mathrm{KCl}, \mathrm{CH}_{3} \mathrm{OH} \) and \( \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{11} \mathrm{OSO}_{3}{ }^{-} \mathrm{Na}^{+} \)at room temperature. The correct assignment of the sketches is
(A) \( \mathrm{I}: \mathrm{KCl} \quad \mathrm{II}: \mathrm{CH}_{3} \mathrm{OH} \)
III : \( \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)-{ }_{11} \mathrm{OSO}_{3}^{-} \mathrm{Na}^{+} \)
(B) \( \mathrm{I}_{2} \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)-_{11} \mathrm{OSO}_{3}^{-} \mathrm{Na}^{+} \quad \) II : \( \mathrm{CH}_{3} \mathrm{OH} \quad \) III : \( \mathrm{KCl} \)
(C) \( \mathrm{I}: \mathrm{KCl} \quad \) II : \( \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)-{ }_{11} \mathrm{OSO}_{3}^{-} \mathrm{Na}^{+} \quad \mathrm{III}: \mathrm{CH}_{3} \mathrm{OH} \)
(D) \( \mathrm{I}: \mathrm{CH}_{3} \mathrm{OH} \quad \) II : \( \mathrm{KCl} \quad \) III : \( \mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)-_{11} \mathrm{OSO}_{3}^{-} \mathrm{Na}^{+} \)
