Answer:
a). The partially charged regions of polar molecules are able to form hydrogen
Step-by-step explanation:
Polar molecules :
Those molecules in which positive and negative charge are distributed in random order or unevenly.
The shape of bond between hydrogen and oxygen atoms in water is bend shape that is why water act as polar molecule.It means that most positive charge collect on the hydrogen molecule and most of negative charge will collect on oxygen molecule.
So the our option a is correct.
