If the Difference in Electronegativity Between Two Elements in a Compound

If the difference in electronegativity between two elements in a compound is very small (less then 0.2) , can you safely conclude that the compound formed from the two elements is covalent?

A) Yes, because a small difference in electronegativity always indicates that a compound is covalent.
B) No, because covalent compounds are formed between two elements with a large difference in electronegativity.
C) Electronegativity has nothing to do with whether a bond is covalent or not.
D) No, because a metallic compound could also be formed between two elements with a small difference in electronegativity.
E) None of the above are correct.
