Solution
The correct option is A germanium
Potassium is one of the major electrolytes (together with sodium, chloride and magnesium) thatconducts electricity in the human body. Gallium does not conduct electricity, Chromium is a (transition) metal and conducts electricity. Germanium is a metalloid. Therefore, it is neither a good conductor of electricity nor an insulator.
