From the following (b) "Unequal sharing of electrons among atoms" is true about polar covalent bonds.
A polar covalent bond is formed between two atoms if the difference in electronegativity between them is between 0.5 and 2.0. Or when two non-metals come together, they can form polar covalent bonds. A dipole moment is created when two elements differ in their electronegativity, and it always points in the direction of the more electronegative element. Since this process involves the sharing of electrons rather than the transfer of electrons, partial charges are produced. So among the given options only option (c) Unequal sharing of electrons among atoms" is true about polar covalent bonds, is the correct one.
