Which statement below correctly describes the bond between carbon and oxygen in a compound?

a
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is nonpolar covalent.
b
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is ionic.
c
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with carbon pulling the electrons toward it.
d
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with oxygen pulling the electrons toward it.

The correct statement is:

c Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with carbon pulling the electrons toward it.
