This iron oxide is polar-covalent.
polar
Non polar
If "polar" and "nonpolar" are the two options, your best bet will be nonpolar. However, rust (iron III oxide or Fe2O3) isn't generally classified based upon its dipole moment. The molecule overall is an ionic compound that is minimally soluble in water and is typically classified under inorganic headings rather than the organic chemistry distinction of polar/nonpolar.
polar covalent

yes
It's ionic, not polar

There are two isomers of Ethenediol. One is polar and the other is nonpolar.
It's ionic, not polar
yes. yes it is.
It is non polar

Cl4 does not exist, but if CCl4 is meant: this is a nonpolar compound
