Diatomic molecules will be non polar when

B) both atoms are the same element.

Explanation: -

Non polar means the electrons in a bond between the two atoms are present at the same distance from the two atoms.

The electrons get closer to one atom over the other if the electronegativity if different.

The difference in electronegativity arises due to different number of protons.

Thus, Diatomic molecules will be non polar when

B) both atoms are the same element.
