As we have learnt, 

Tyndal effect is observed only when 

(I) The diameter of the dispersed particles is not much smaller than the wavelength of the light used

(II) The refractive indices of the dispersed phase and the dispersion medium differ greatly in magnitude.

Hence, the correct answer is Option (1)
