Answer: Option (a) is the correct answer.
Explanation:
A water molecule contains two hydrogen atoms and one oxygen atom. The chemical formula of water is .
Here, hydrogen is electropositive whereas oxygen atom is electronegative in nature. Hence, oxygen atom pulls electrons from hydrogen atom and as a result partial positive charge develops on hydrogen and partial negative charge develops on oxygen atom.
Therefore, molecule of water becomes polar in nature.
Thus, water is considered a polar molecule because it has partial positive and negative charges at each end.
