Answer:

CaO- ionic

InAs-covalent

Al2O3-ionic

Bronze- metallic

Explanation:

CaO and Al2O3 are mostly ionic even though the posses a little covalent character but ionic bonding is the main bonding scheme. Bronze is an alloy of two metals hence it contains a metallic bond. InAs has an electro negativity difference of 0.4 between the atoms so it is a polar covalent bond.
