(C) Hydrogen bonding.
▪ Hydrogen bond causes the attraction between water molecules.
▪ Inner molecules are attracted evenly from alld irections. But surface molecules have unbalanced force caused by inner pulling. This is surface tension.
▪ Thus causes the net upward force in upper layer of water. This helps striders to walk on water.
