#6 B b/c O is partially negatively charged, H partially posi

Positively charged in O-H, C-H, C-O, O-Hcovalent bonds. 
#3 B b/c cohesion is the attraction between molecules. E.g. via hudrogen bond like in #6. Adhesion describe cells. Due to hydrogen bond, water molecules are "sticky" on molecular level. So it has high surface tension. It's why it transpires in plants, why it moves up in xylem in plants. Due to its cohesive nature.
