Brief Explanations:

A nonpolar molecule can contain polar bonds. In a nonpolar molecule, the polar bonds may be symmetrically arranged. For example, in (CO_2), the (C = O) bonds are polar (because of the electronegativity difference between (C) and (O)). But the molecule is linear, and the dipoles of the two (C = O) bonds cancel each other out ((\vec{\mu}=0)). So the overall molecule is nonpolar despite having polar bonds.

Answer:

No, I do not agree. A non - polar molecule can contain polar bonds. For example, (CO_2) has polar (C = O) bonds (due to electronegativity difference between (C) ((2.5)) and (O) ((3.5))). But because of the linear geometry ((O = C=O)), the bond dipoles cancel each other ((\vec{\mu}=0)), making the (CO_2) molecule non - polar.
