The correct option is A Water
Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity.
The larger the difference in electronegativity, the larger the dipole moment.
The distance between the charge separation is also a deciding factor in the size of the dipole moment.
The dipole moment is a measure of the polarity of the molecule.
