Explanation:

Water cohesion is due to hydrogen - bonding which arises from the partial charges on water molecules. The oxygen in water has a partial negative charge and the hydrogens have partial positive charges, allowing water molecules to attract each other. For the second question, a polar covalent bond occurs when there is a significant difference in electronegativity between the two atoms in the bond. However, since the options for the second question are not shown, we can only answer the first one.

Answer:

C. partial charge
