B. Covalent Bonds: These bonds are formed when there is sharing of electrons between the two atoms.
C. Metallic bonds: These bonds are formed from the attraction between the free electrons and fixed positively charged of two metallic atoms.
D. Polyatomic Bonds: These bonds are formed between the species forming a polyatomic ion.
From the given information, the correct answer to this question is Option A.
