Answer: The correct answer is Option D.
Explanation:
A non-polar covalent bond is defined as the bond which is formed between the atoms having no difference in electronegativity values. For Example: [tex]Cl_2,H_2[/tex] etc..
In this bond, the electrons are shared equally and [tex]\Delta EN[/tex] value is equal to 0.
Hence, the correct answer is Option D.
