Answer:

The roman numerals in blue are the labels I will write below.

i. lone pair of electrons on oxygen atom

ii. covalent bond between oxygen and hydrogen

iii. partial charges that are due to oxygen's high electronegativity. Oxgen will pull the pair of electrons in the covalent bond towards itself and that obtaining a partial negative charge, while hydrogen obtains a partial positive charge.

iv. hydrogen bonds between partially negative oxygen and partially positive hydrogen.

PS. EACH WATER MOLECULE CAN MAKE UP TO 4 HYDROGEN BONDS. ONE WITH EACH HYDROGEN AND TWO FOR EACH ELECTRON LONE PAIR ON OXYGEN. (refer to the middle water molecule in the diagram)
