AN is more polar because of it electron negativity charge ex. N electron negativity charge is 3.0 and H is 2.1 
 B) C is more polar...electron negativity for C is 2.5 AND H is 2.1 
 C)O is more polar dues to it electron negativity charge being greater that hydrogen 
 D)H and H are both non polar because they cancel each other out due to the face the both share the electron negativity evenly
