Answer: A) polar molecule
Explanation: Polar molecules are molecules which contain atoms of different electronegativities.
Non polar molecules are molecules which contains atoms of same electronegativities.
Water is a polar covalent molecule formed by unequal sharing of electrons. Oxygen being more electronegative tend to keep the electron pair towards itself thus generating a partial negative charge. The hydrogen acquire a partial positive charge thus resulting in a polar molecule.
The bent shape is due to repulsion between lone pairs and bond pairs of electrons.
