Best answer
Correct option is (c) paramagnetic

For explanation I would say: All the superoxides of alkali metals are colored and paramagnetic, as they possess three electrons bond where one unpaired electron is present. Few examples of superoxide are potassium superoxide, rubidium superoxide, and cesium superoxide.
