Mark the incorrect statement

(1) Fructose, mannose and some amino acids are

      absorbed by facilitated diffusion 

(2) Various nutrients like amino acids, fatty acid,

     monosaccharides like glucose, electrolytes like

     ${\mathrm{Na}}^{+}$ are absorbed by active transport only 

(3) Fatty acid and glycerol are first incorporated 

     into small droplets called micelles which move

     into intestinal cell of mucosa 

(4) Transport of water depends upon osmotic
