Explanation:

{c}^C . {d}^D / {a}^A . {b}^B

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is c.the valence of the atoms combine .
