(a)
Interpretation: The identification of polar molecules is to be done and the direction of the net dipole is to be shown if one exists.
Concept introduction: The polarity of a molecule depends upon the electronegativity difference between the atoms. The electronegativity difference predicts the directions of bond dipoles. A polar molecule possesses net dipole, whereas a non-polar molecule does not possess net dipole moment.
