Two Elements in a Molecule Have the Same Electronegativity Values

Two elements in a molecule have the same electronegativity values. Which of the following most likely holds the elements together and why?

A) an ionic bond, because electrons transfer from one element to the other
B) a nonpolar covalent bond, because the elements share electrons equally
C) a polar covalent bond, because the elements do not share electrons equally
D) an intermolecular force, because the elements do not form a chemical bond
