Answer:

A. Polar covalent bonds exist between atoms of the same element.

Explanation:

A polar covalent bond is the result of an unequal sharing of electrons, this means that there's a electronegativity difference between the two elements high enough for it to become polar, but not high enough to become completely ionic.

Two atoms of the same element have exactly the same electronegativity, meaning there's no difference in electronegativity, meaning it's not possible for polar covalent bonds to exist between atoms of the same element.
