The qualitative sketches I, II and III given below show the variation of surface tension with molar concentration of three different aqueous solutions of KCl, $$CH_3OH$$ and $$CH_3(CH_2)_{11}OSO_3{^-Na^+}$$ at room temperature. The correct assignment of the sketches is

A

I. $$KCl$$ II. $$CH_3OH$$ III. $$CH_3(CH_2)_{11} OSO {^-Na^+}$$

B

I. $$CH_3(CH_2)_{11} OSO {^-Na^+}$$ II. $$CH_3OH$$ III. $$KCl$$

C

I. $$KCl$$ II. $$CH_3(CH_2)_{11} OSO {^-Na^+}$$ III. $$CH_3OH$$

D

I. $$CH_3OH$$ II. $$KCl$$ III. $$CH_3(CH_2)_{11} OSO {^-Na^+}$$
