Choose: "The electronegativity differences between carbon and oxygen are not very large."
Explanation: molecular polarity depends on differences in electronegativity and how charge is distributed. C and O differ in electronegativity by only about 0.9, so CO is only weakly polar. (Note: CO is not completely nonpolar — it has a small dipole moment ~0.11 D with the carbon end slightly negative — but it is far less polar than many heteronuclear bonds.)
