The borax bead test is a procedure used in qualitative inorganic chemistry to detect the presence of certain metals. The bead test involves dipping a loop of wire in a solution of the metal, then into powdered borax, and heating it in a flame. The borax reacts with the metal to form a colored borate which can be used to identify the metal.

In the case of Cobalt (Co2+), the borax bead test results in a blue colored bead. This blue color is due to the formation of Co(BO2)2. Therefore, the correct answer is CCo(BO2)2.
