Letter B

Br & I are both nonmetals. They will share e- while the other choices are metal & nonmetal -- they will form an ionic bond with no sharing of e-.

Sharing of electrons produces a covalent bond. As a general rule covalent bonds occur between two non-metals.

Transfer of electrons produces an ionic bond. As a general rule ionic bonds occur between a metal and a non-metal.
