Answer: must be nonpolar

Step-by-step explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms. Example:
HF

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms. example:
Cl_2

Thus as
H_2 ,
N_2 ,
O_2 molecules are formed by similar atoms with no electronegativity difference, the bond must be non polar.

Hence, the correct answer is the molecules
H_2 ,
N_2 ,
O_2 must be non polar.
