Solution
The correct option is B Cadmium The 38 elements in group 3 through 12 of the periodic table are called "transitional metals". These metals are both ductile and malleable and conduct electricity and heat. There are only 3 elements that produce magnetic fields which are iron, cobalt, and nickel. However, cadmium though included in transition metals does not generate a magnetic field.
